海外TECH	DEV Community	Practical limits of React hooks - Recursion	https://dev.to/ondrejvelisek/practical-limits-of-react-hooks-recursion-555	Practical limits of React hooks RecursionWhile ago I started using React hooks The simplicity homogenity and composability sounded great Both components and hooks are simple functions I can easily react on state changes from memory local storage location URL and server the same way with hooks Mental model stays simple My app is just a big function which consumes state and produces DOM This big function is composed of a smaller functions which are composed of smaller functions and so on But there were obstacles I ve started to encounter and in the end I hit the hard limit of React hooks Model appEach app has some data model defined with entities and relations between them Lets say we have company Department and Employee where department consists of other departments and or direct employees One employee can directly work for exactly one department Cycles in department hierarchy are prohibited Our Backend implements REST endpoints departmentsreturns list of all department ids departments departmentIdreturns list of sub department ids and list of direct employee idsThere are three product requirements Pleasant walk with basic hooksFirst product requirement is simple User selects a department and wants to see number of direct employees Pfff its simple Just implement this custom hook which uses department REST endpoint and use it in a component const useDirectEmployeeCount departmentId string number gt useDirectEmployeeIds departmentId lengthconst useDirectEmployeeIds departmentId string Array lt string gt gt useDepartment departmentId directEmployeeIdsconst useDepartment departmentId string Department gt useQuery departments departmentId gt fetch departments departmentId dataOur backend implements exactly this endpoints so we use react query and we are done There are some loading and error states which I omitted we can use fancy Suspend and ErrorBoundary but we understand the code Obstacles with loopingSecond product requirement is simple User needs to select multiple departments and see sum of direct employees Ok simple I already have code for one So simply loop it over multiple selected departments and sum the result const totalCount sum departmentIds map departmentId gt useDirectEmployeeCount departmentId Wait It is a hook and there are rule of hooks Anoying but still doable Lets reimplement useDirectEmployeeCount to support multiple department ids Then I can sum them like this const departmentCounts useDirectEmployeeCount departmentIds const totalCount sum departmentCounts const useDirectEmployeeCount departmentIds Array lt string gt Array lt number gt gt useDirectEmployeeIds departmentIds map employeeIds gt employeeIds length But wait I need to reimplement useDirectEmployeeIds too Very anoying const useDirectEmployeeIds departmentIds Array lt string gt Array lt Array lt string gt gt gt useDepartment departmentIds map department gt department directEmployeeIds But wait Grrr const useDepartment departmentIds Array lt string gt Array lt Department gt gt useQueries departmentIds map departmentId gt queryKey departments departmentId queryFn gt fetch departments departmentId map result gt result data Uf Done I m glad it is a small project with just three hooks Tell me the last requirement Limits with recursionThird and last product requirement is simple User needs to select department and see sum of direct and indirect employees including employees from all sub departments and their sub departments and so on Ok simple I already have code for multiple departments So simply recursively call it and sum the result const useIndirectEmployeeCount departmentIds Array lt string gt Array lt number gt gt const directCount useDirectEmployeeCount departmentIds const departments useDepartment departmentIds const subDepartmentIds departments flatMap department gt department subDepartmentIds const indirectCount useIndirectEmployeeCount subDepartmentIds return directCount indirectCount Wait Error Maximum Call Stack Size ExceededOh You almost got me I just forgot a recursive break right const useIndirectEmployeeCount departmentIds Array lt string gt Array lt number gt gt const directCount useDirectEmployeeCount departmentIds const departments useDepartment departmentIds const subDepartmentIds departments flatMap department gt department subDepartmentIds if subDepartmentIds length return directCount const indirectCount useIndirectEmployeeCount subDepartmentIds return directCount indirectCount Wait Error React Hook useIndirectEmployeeCount is called conditionally Last wordsMental model stays simple Everything is a simple function My app is one big function composed of smaller and smaller ones It trully sounds great But in a real world hooks are not so simple homogen and composable There are obstacles and limits mainly because of rule of hooks This post is not about saying React hooks are bad I wrote it because I did not find any resources on such obstacles and limits The React world looks like hooks are always pleasant walk trought the rosy garden But they are not For now I don t know how to elegantly solve the recusrion example Are there some resources on this Do you have following thougts Maybe I m not the only one struggling

海外TECH	DEV Community	How to Answer "Tell Me About Yourself" Interview Question for Tech Talent	https://dev.to/hired_hq/how-to-answer-tell-me-about-yourself-interview-question-for-tech-talent-5edd	How to Answer quot Tell Me About Yourself quot Interview Question for Tech TalentRegardless of whether you re a software engineer a data scientist a web developer or a program manager you ll be asked “tell me about yourself in nearly every interview It s a popular way to get the ball rolling and if you answer it well you set the tone for a successful interview In this article we ll cover How to begin the interview traps to avoid when answering “tell me about yourself ways to prepare and confidently deliver your answerHow to craft a strong answer using a job descriptionA summary of the steps to nailing this question How You Start An Interview Can Be Just As Powerful As How You End OneLet s start this conversation from when you meet the interviewer Everybody talks about the ever so important handshake right If you re in the position for an in person interview be sure to look them in the eyes and give them a nice firm handshake demonstrating confidence Zoom interviews may have you out of practice so if you re visiting as part of an on site or simply networking give a confident but brief grip The worst thing you can do is give the “dead fish handshake Blech That can be the kiss of death before the interview even starts Meeting for the first time online Check out our article on Video Interviews First I suggest striking up some small talk to build rapport before the interview even begins This will allow you and the interviewer to informally get to know each other Plus this can help calm your nerves a bit Whether you re meeting a recruiter or a panel of interviewers be sure to ask the scheduler for their names ahead of time if they re not provided Look them up on LinkedIn and any other social media You might discover you have mutual connections or other things in common giving you an opportunity to talk about something other than the weather Before We Dig Into Answering “Tell Me About Yourself… Please don t let this question stress you out Interviewers tell me all the time they want you to nail the interview They are actually rooting for you Keep in mind they want to interview you because your resume showed you have the skills to do the job They wouldn t waste their time bringing you in for an interview if they didn t think you were a good candidate This applies to ALL jobs The good news is “tell me about yourself is a question you should nail every time because you know it s coming have the job description to prepare with and have the time to practice Now let s break this down Traps What To Avoid When Answering “Tell Me About Yourself We ve all been guilty of one or more of these in the past Let s recognize them note them and move on Please I m begging you do not start with “Hi my name is… Without fail of people will start their answer this way This isn t necessary because they asked you to interview They have your resume with your name plastered across the top hopefully Without fail though people state their name again Do not restate what is already on your resume Sometimes if the interviewer hasn t read your resume they may ask you specifically to review your resume That is a completely different question Don t ask them to clarify the question “Do you want me to talk about my education personal life or experience You should know exactly how to answer this question Don t reply with a modest or vague introduction that doesn t communicate your strongest qualifications for the position Never shy away from selling yourself Stay away from the personal side of your life when answering this question This is not a date or an invitation to tell your life story This can be longer than seconds You use your “elevator pitch when networking They call it an elevator pitch for a reason You don t have much time to answer so you need to be succinct and straight to the point You have more time in an interview so use it The rule of thumb however is don t go over minutes Try not to ramble It happens when we get nervous I know Take a breath Use the time to provide enough information to give an overview of What skills and experience do I have that align with the role And how can I provide value to the organization based on my experience Now that we know what not to do let s talk about how to Knock It Out Of The Park Keep in mind when you skillfully answer this question it s a great indicator you know how to interview Undoubtedly this will bring a smile to the interviewer s face They might even sigh in relief Ways How to Prepare and Instill Confidence with Your Answer Practice builds confidence Answering this is not easy to do gracefully on the fly It pays to prepare in advance Trust me on this one Rehearse your answer in the car or in the shower Record yourself and play it back If you cringe try it again Preparation is key to crushing this question and success Practice with a friend or family member The more you practice the better For those of you who love to wing it…please don t You can thank me later Align with the job descriptionYou re going to want to craft your answer by highlighting technical and soft skills aligned with the job description Concisely convey them through specific projects work experience and or education Try the stacked blocks method of progressionOne way to structure how you answer this question is by thinking of your previous roles as building blocks to your current role In each “block highlight expertise in a language framework or skill you learned or used Be sure to spotlight skills or languages they ve asked for in the job description Make it easy for them to see what a great match you are Identify your main selling points for the roleThis could be years of experience or a specific area of specialization Highlight special training or a Bootcamp experience By focusing on the qualifications in the job description you ll be able to tell them how you will meet and exceed requirements Make your pitch in your closingDescribe why you re interested in the position Maybe indicate why you are looking for a new challenge and why you feel this role is the best next step Are you ready to move from being an individual contributor to a team lead Maybe you re looking for more autonomy or opportunities to influence the roadmap Be sure to focus on how you will provide value by reinforcing how your experience skills and drive can help them reach their goals Finally feel free to incorporate any relevant hobby or volunteer experience If they match traits in the job description such as attention to detail or collaboration with others they re relevant Maybe you build websites or troubleshoot IT issues for nonprofits in your community Perhaps you coordinate volunteers or coach a team Maybe you re not using a specific language in your current job but use it as part of an ongoing passion project Share these things Let s Put It All Together With This ExampleLet s craft an example using the job description below Sample Job Description Use a variety of technical skills soft skills and industry knowledge to develop applications and systems Expertise in C C Java Python JavaScript C PHPUse analysis and critical thinking skills to determine and assess the needs of the user and then create software to meet the requirements Ability to collaborate and provide clear instructions to the project team clearly explaining how the software looks to the customer Available to answer any questions using exceptional communication skills Apply keen attention to detail and organizational skills to work on numerous parts time management of a system or application at the same time while being accurate and thorough Able to work well and collaborate with others on a team of Designers Developers and Programmers using effective interpersonal skills Able to efficiently identify and resolve issues during the design testing and maintenance process using strong problem solving skills Example Response “So tell me about yourself… “Thank you for asking I would describe myself as a collaborative and solution driven software engineer with over two years of experience working with designers developers and programmers holding a degree in Computer Science from Purdue University I ve already contributed to over a half dozen projects and assisted with managing a project for one of our firm s long time clients Something I ve enjoyed and has been able to use in my current role is leveraging my experience in tech support to help identify and resolve complex issues And over the last year I worked on several project teams using C Python JavaScript C and PHP and recently started Java Since this role asked for Java I signed up and started an online Java course to increase my knowledge as quickly as possible I believe my experience has allowed me to hone my attention to detail and critical thinking skills as well as enhance my communication skills working on team based projects and with clients In my last role in tech support I received several commendations from customers where I was able to identify and resolve their technical issues with clarity and ease I m excited to collaborate on a team and apply my technical skills to develop applications and systems along with contributing to your team in a way that positively impacts the organization and your clients See how we matched up the job description specifics with the response In Conclusion Tell Me About Yourself Doesn t Need To Be So Scary Note how in the example above you didn t see “I was born in or “I grew up in types of autobiographies It boils down to Who you are“I m a characteristic description title with number years of experience working with teams functions or industries holding a education How you got here“I ve contributed to types or number of projects managed types or number of projects and used my experience to something from the JD they need you to do I ve used languages skills and achieved example of success contribution or something you learned Why you re here“I m eager to what excites you about the role apply my skills to tasks projects or function and contribute to positive outcome or goal of the team company etc In a nutshell remember these five steps Focus on the job you are applying to Think about what makes you stand out Include your technical and soft skills that align with the role Mention past accomplishments End strong with how you can provide value to the company It may help to write out your response and read it aloud several times before your interview The goal is not to memorize it per se You want to be authentic But writing it down helps organize your thoughts If your interview is over Zoom it s easy to have notes and bullet points on a second screen or nearby Just don t “read it It s your story after all You know it The best advice I can provide as a Career Coach is to prepare and practice I ve seen hundreds of people move from literally having no idea how to navigate the “tell me about yourself question to absolutely killing it You ve got this Ready to find your next role Employers are looking for tech professionals now Here s how it works for job seekers

海外TECH	DEV Community	Exception Breakpoint that Doesn't Suck and a Real Use Case for Method Breakpoints	https://dev.to/codenameone/exception-breakpoint-that-doesnt-suck-and-a-real-use-case-for-method-breakpoints-2bbc	Exception Breakpoint that Doesn x t Suck and a Real Use Case for Method BreakpointsTwo weeks ago I left this series in a “cliffhanger of sorts Well as much as a programming blog can leave things in the air…The big one amongst them is the premise that exception breakpoints don t have to suck If you used them in the past you would know that grabbing all exceptions is ridiculous You end up at a breakpoint every second and it doesn t help There s a solution and it s discussed in duckling number also covers a lot of interesting ground for us and another cliffhanger on method breakpoints Shai Almog debugagent Duckling the th Remember I told you not to use method breakpoints Except for one use case Here it is and it s amazing Did you know you can see all the object instances of a given type in the VM That and more CodeNewbie SecondDucklings PM Mar FiltersFilters solve the problem of “noisy breakpoints They let us limit a breakpoint to a very specific narrow area which we can then inspect more casually When debugging a major project this is an invaluable tool at our disposal Catch ClassThis one feature makes exception breakpoints worth having But let s back up a bit and discuss the problem…At least for JVM languages For a typical web request Java needs to perform many operations for which the only response is an exception E g a URL request would require header parsing If a number in the header differs from what you expected a NumberFormatException will be thrown…It s caught inside the JVM implementation since it s expected But the exception breakpoint support will still break for this and many other exceptions in the JVM code For any non trivial applications this is a problem The solution is simple Filter out the catching classes if they are in the java or sun root packages We can do this in the current breakpoint dialog using the filter java sun notice the character used to filter out the packages This one small class filter will remove that redundant noise and let you focus on exceptions that you catch or don t An uncaught exception is almost always useful in the debugger as it can lead to an application fatal error You can add additional filters to cover other libraries and your own classes as needed This is a remarkable feature Of all the breakpoint types I feel these have the most untamed potential I hope more people turn this on by default with this filter which should itself be the default InstanceThis limits the breakpoint to the current object This is something I would normally use a conditional breakpoint for The problem is that conditions might cause a mistake e g in a case where instances are harder to differentiate Conditions also require more work When applying an instance filter you need to get the object ID from the watch and use that for the field ClassClass filter seems redundant at first until we look at the more elaborate breakpoints we have in place A good example is field watchpoint which can be triggered by access from a different class assuming the field isn t private Let s say you have a public field and you re concerned someone is reading or writing to it from outside of your class Your code can t be changed as there s too much legacy Usage info shows you who s using it but it s spread all over the place You just want to see if someone from outside the class is physically accessing the field at this frame of time In that case you can add a class filter to only break in the field watch point for access that isn t from the set of classes CallerHave you ever reached a breakpoint and looked at the stack Then kept pressing continue until that stack changed to include the method you wanted in the stack The one that invoked your call This is where the caller filter comes in You can exclude a specific stack element from consideration or require a specific method Method BreakpointYou may recall I mentioned you shouldn t use method breakpoints They re usually just emulated by line breakpoints to avoid their typical overhead So there s no actual need for them when placing one on a method But there s another approach You can add a breakpoint using filters names e g you can add a breakpoint to all the methods starting with the word is in all the classes starting with the word Prime as we can see here This might sound excessive but there s a common and valid use case Imagine using a complex polymorphic API that follows a naming convention It s hard to know which method is invoked to handle which behavior This way you can grab all suspects using a simple pattern So how do you deal with the excessive noise We can use a conditional breakpoint just like we can in any other area of the program We can use tracepoints and pretty much any other option in the list above Show ObjectsFor the last section I m going to go to the watch instead of the current breakpoint discussion This is a feature that s so cool and so simple Yet unfamiliar to many developers When you right click an Object in the IntelliJ watch you can ask to show all objects This literally means ALL OBJECTS in the process When you do that on a Thread object you see the JIT compiler thread You can see internal JVM const message strings when doing it on a String array When you re looking at a specific object and wondering is this the right instance well You can review all instances and verify with a right click You can even narrow down that list with an expression statement to make it even more useful for a larger list of objects TL DRI hope this blew your mind There are so many debugger capabilities that we sometimes gloss over when trying to build an application The tools we discussed today are all designed for debugging large code bases Where the capabilities of these tools really shine These tools let us easily define complex logic in runtime that can lead us directly to the problem area in the application code When you incorporate these capabilities into your debugging process it will pay back with dividends	2022-03-22 16:08:46
海外TECH	DEV Community	Javascript Map, and How it is Different from forEach	https://dev.to/smpnjn/javascript-map-and-how-it-is-different-from-foreach-1j1i	Javascript Map and How it is Different from forEachThe map method is one of the most used functions in Javascript It is used to take arrays and return a new array which can be changed with an attached function When you start developing in Javascript you ll see map everywhere Let s look at how it works How map works in Javascriptmap is a method of arrays That means you can only use map on something which is typed as an array For example map will work but map will not The map method itself accepts one function Let s look at an example let arr let mappedArr arr map item gt return item Returns console log mappedArr map goes through each item in an array and returns in its place whatever you modify it with in the map function Above we take every item in our array and multiply it by We store this new mapped array in a variable called mappedArr It s important to note that map doesn t modify the original array It simply creates and returns a new array which we can store in a variable should we choose to You can modify the array in any way that you like including by adding strings Whatever you return in the map function will replace that particular item in the new array let arr let mappedArr arr map item gt return Number arr Returns Number Number Number Number console log mappedArr Arguments in map functionAs shown above we can access the item itself in map but we can also access other useful things relating to the array let arr let mappedArr arr map item index array gt return Number arr The above is the same function as before but showing the arguments available to you when you use the map function item this is the value of the current array item being looped through index this is the index of the array that we are currently at So if we are on the nd element in the array the index will be since it starts counting from array this is the full array map was called upon which we can access if we need to This gives us a lot of flexibility in how we can manipulate an array using map Difference between map and forEachYou might see map and forEach being used interchangeably The difference between both of these is that forEach loops through an array but doesn t return the array at the end map on the other hand returns a new array when it s used Therefore you might want to use forEach if you don t want to return a new array at the end of your function Conclusionmap is used extensively in Javascript as arrays are a major part of handling data in the language If you are interested in learning more about arrays check out the cheatsheet I wrote here	2022-03-22 16:05:31
