海外TECH	DEV Community	The tricks of Javascript	https://dev.to/noriller/the-tricks-of-javascript-3pn	The tricks of Javascript Here s a trick question const arr Array fill const arr arr map subArr i gt subArr push i What is the final value of arr And the final value of arr This might be something you see people asking in an interview and before you go console log arr arr it s important to know the why more than the answer An array is a value that will always be passed “as reference which means it s pointing somewhere in memory and it simply uses that In contrast a value like a string or a number is passed “by value meaning it s copied to where it s needed And as weird as it might seem when you say it to fill with you re telling Javascript to use the same reference in all instances So when you map you re pushing the index to the same reference over and over What about the second one then Well that s even more trick Because that s just what push returns And if you didn t know push returns the length of the array after the push And since it s inside a map that returns a new array it s easy to understand what s going on The resultAnd so it prints this arr arr And not gonna lie This didn t come from an interview or anything like it but from a test I was doing that as you might have imagined wasn t doing what I wanted it to do The “fix const arr Array fill map gt const arr arr map subArr i gt subArr push i console log arr arr arr arr Just Array map gt doesn t work since Array n creates an array of “empty slots that you can access directly but you can t do much else so you need the fill to replace those “voids with undefined Why does this work This one works because map iterates over the array and each of the is actually a new object that is passed by reference since each iteration uses a new scope If you were to initialize a outside and pass it then we would be back to square one Cover Photo by Natalia Y on Unsplash	2022-01-30 21:38:05
海外TECH	DEV Community	Six Steps to Tackle Any Algorithm	https://dev.to/jonathanbryant19/six-steps-to-tackle-any-algorithm-28a4	Six Steps to Tackle Any AlgorithmOne of the best things about programming is experiencing that moment when everything clicks the program works and the problem is solved I love that feeling and I don t think I m alone You know what sucks though That moment when the code doesn t work you have no idea why and you re being timed That s not a good feeling and again I don t think I m alone I recently started a software engineering bootcamp at Flatiron and have had a steady diet of both feelings over the past few weeks However as part of the curriculum I recently received an algorithm for solving algorithms At first I thought the extra work was well just extra work but having a mental framework to leverage when the way forward isn t clear has proved to be invaluable Here is a coding challenging I worked through on Codewars Honestly this is a challenge I would have passed on until recently but armed with a handy problem solving framework I managed to solve it Here s how I broke down the problem step by step Rewrite the Problem in Your Own WordsHere is the question as written on Codewars Your goal in this kata is to implement a difference function which subtracts one list from another and returns the result It should remove all values from list a which are present in list b keeping their order Rewriting helps clarify several things in particular the input and output data types I ve found it s helpful to look at any test conditions if provided to see if there are special circumstances to consider e g blank arrays invalid inputs etc I rewrote the problem as follows You are given two arrays of numbers as inputs Take each number in the second array and remove all instances of that number from the first array Return an array of the remaining numbers Write Your Own Test Cases This doesn t mean you actually have to write code for unit tests Simply writing a few instances of the input and expected output of a function can help ensure all expectations of the challenge are considered function arrayDiff a b arrayDiff returns arrayDiff returns Pseudocode the solution Personally this is one of the most valuable steps for me Writing out how to approach the problem step by step in plain english provides an outline for how to go about solving the problem This is especially critical as the complexity of the challenge increases Another reason to pseudocode is to demonstrate how you would approach a problem even if you can t ultimately solve it If I were given a problem I m unable to solve in an interview I d rather show the interviewer what I know than sit there in a catatonic stupor Iterate through the first array and look for the first value of the second array maybe a for loop a If the value exists in the first array delete it maybe using splice Repeat the process for each value in the second array I might need a nested loop here Return a single array of values Code a solution Now that we have an outline it s time to put some code together Here s what I had for my first attempt at completing step function arrayDiff a b for i i lt a length i if a i b a splice i console log a arrayDiff returns This looked promising at first but I wasn t getting consistent results using my tests I found that using splice this way allowed for repeats to slip through the cracks because of the way the placement of values in the array shift every time splice is used To prevent this I iterated through the array backwards function arrayDiff a b for i a length i gt i i if a i b a splice i console log a arrayDiff returns This solves step for me but the function does not allow for the b array to be longer than one number All I need to do at this point is figure out how to loop through the second array This was my attempt function arrayDiff a b for j j lt b length j for i a length i gt i i if a i b j a splice i console log a arrayDiff returns It works At this point I have code that does it s job but there are two more steps before I m ready to submit Clean Up the CodeA quick review of the function helps to ensure indentations and variable names are clear and clean I don t have any variables to worry about but my i and j variables really should be switched Also I can iterate through the loop backwards by changing j j to j I ll also change my console log to return function arrayDiff a b for i i lt b length i for j a length j gt j if a j b i a splice j return a Consider OptimizationAt this point in my learning I m just beginning to explore optimization I wasn t a fan of using a nested loop and I was fairly sure there was a better way to go about solving this One of the things I love most about Codewars is the feedback you get after submitting a correct solution I ve had many forehead slap moments after seeing a solution much easier than my own Here s what Codewars provided as the top answer under Best Practices function array diff a b return a filter e gt b includes e This was definitely a forehead slap moment I hadn t considered using filter in conjunction with includes Also this was also the first time I ve seen the bang operator used with an array method I ll just go ahead and repeat this process a few thousand times and I think I ll be well on my way to increasing my
