海外TECH	DEV Community	30-Day React Learning Journey! [part 1]	https://dev.to/ymhaah/30-day-react-learning-journey-part-1-14od	Day React Learning Journey part Introduction After a lot of procrastination and giving myself a million reasons to not start like I will finish another project I can do everything without it right now I don t need it I don t like Facebook React Made by Facebook I have to master JavaScript first said no one I finally decided to start learning React And for every programmer who once felt that he did not deserve to be a programmer at the beginning of any course I decided to record my trip in all its details Since if I succeed in learning it at the current level of my intelligence I will prove that learning programming depends more on luck than on intelligence So in today s article I will talk about my journey in learning React learning resources tricks easy and hard stuff and I will try to summarize what I learned quicklyas the main objective of this article is not to teach you React I don t think anyone wants a teacher with only days of experience Notes Any mistakes or lack of information will be corrected After the blogging part I will attach a link to any feature I will use if you want to know more about it and of course I will explain to you why I used it specifically For credibility I will also attach the original source which I learned a trick from Follow me on Twitter where I post almost daily about my journey in learning programming TwitterAll the code shown in this article and more can be found here GitHub Day React Learning JourneyWithout further ado let s get started with my Day React Learning JourneyHonestly I don t know if I ll take days to finish React or not but I just chose it because it looks good in the title day Choosing the course One of the main reasons why I haven t started learning React is because my favorite Mentor hasn t published a React course yet Elzero Web School He is my favorite Mentor and a legend in the Arab dev communityAlthough it will be somewhat difficult to find a course that I like but I am not a beginner in the field I ve taken many courses in many areas before this so I kind of know what good sources are from bad sources even before I start Although I will often learn from one source I will share with you all the courses that I think are goodSo let s start looking for the best course for me YouTube As usual we will find a freeCodeCamp course a lot of I think they cooperated with every potential Mentor So their courses will be on a special list A lot of videos on the type of learning React in minutes or how to learn React the learning path of ReactBut after a quick search on YouTube I found these sources a freeCodeCamp Scrimba courseScrimba is The best course platform in my opinion Where somehow they managed to collect the best Mentor I know in one place like Kevin PoweFull Modern React Tutorial by The Net Ninja I learned bootstrap from him and I had a good experience ReactJS Tutorial for Beginners I just chose it because it is a hour courseThe Complete React Developer Course A small and fast course I will often use this course as a review after completing the restI have ignored any videos that are less than an hour as I do not think that they fit what I need and also all the videos are in English with an understandable accent because I do not want to add any obstacle in the learning processGeneral courses I don t know anyone who learned a skill from reading documents But if there is it will be from React Docs The official website is very good at explaining the content to the point that I may rely on it completely Honesty it is one of the best documents I ve readwschools React Tutorial Classic but I don t like their styleLooking at the average length of the courses with the addition of my laziness perhaps I will finish the React in a month After searching for a long time and reading some articles and watching some videos that I honestly do not remember to share with you the links I decided that this is enough for today and tomorrow we will start learning React day Why React In the beginning most of the courses give an introduction to what is React why we need it what we will learn in the course and what I need to start the course and so on But these are the good courses but The rest is a disaster They start the course without even telling us what React is or what is a library or a framework Without even knowing what I need before starting if you don t know what is NPM You will complete the course thinking you are stupid I think there is a poor programmer Somewhere who learned React before CSS by mistake because of this So let me explain everything you need to know before you get started In order to reach the stage where it is worth learning React you must at least know the following HTML basicsCSS basicsJS basicsNpm basicsAlthough I think that if you only know the basics that you need more time before starting but who am I to stop you from getting a job in six months Of course you need a code editor the Internet and perhaps a computer Second what is React Honestly I am currently still learning and also a bit lazy so I will copy the definition for now React is a free and open source front end JavaScript library for building user interfaces based on UI components Translation React makes the programmers job so easy that they are ready to learn it If you learn sass I think you already know this feeling What is a library A place where pre made codes are collected from people smarter than you so that you don t have to do anything yourself why react React developers are in demand React is easy and fast to learn From what I heard but we ll see All cool boys use it Turns js from a nightmare to a dream or that s what I heardAfter all this talk I think that on the second day despite the little information I learned about it but the introduction was enthusiastic for me The thing I hate the most about the learning process is not knowing why I m learning this thing as I feel in almost all of physics So I spent a lot of time learning about what React is and why I need it so that I don t make the same mistake as I did with pugJs It might be the least useful thing I ve learned I also advise you to delve deeper into that to try to arouse the interest of the little programmer inside you as it will help you complete the learning journey day Getting Started Now after all this talk how do we start using React There are many ways to use React in our projects But basically we need to have React and ReactDOM In our project so that we can take advantage of all the basic properties of React There is something called jsx that we will talk about in the future too CDN LinksReact provides quick links to use all the basic features and It provides two versions of the links development version easy to handle and modify and more suitable in the development stage lt script crossorigin src umd react development js gt lt script gt lt script crossorigin src umd react dom development js gt lt script gt production versions Minified and optimized production versions of React lt script crossorigin src umd react production min js gt lt script gt lt script crossorigin src umd react dom production min js gt lt script gt react recommend to keep the crossorigin attribute set lt script crossorigin src gt lt script gt At the beginning of the courses everyone is advised to use this method for learning as it is easy to use But it is not recommended at the advanced level Where it affects speed and performance But for the educational purpose I will use it for the rest of the trip and we will learn the rest of the ways as well There is an additional link to something called JSX Added without question for now we will talk about it in depth in the future Now you can use JSX in any lt script gt tag by adding type text babel attribute to it lt script src babel min js gt lt script gt lt script src index js type text babel gt lt script gt create react appFor this method I advise you to learn the basics of Npmit is a tool to create single page React applications that is officially supported by the React team When you use it it gives you a set of files that contain what you need to start development directly It sets up your development environment so that you can use the latest JavaScript features provides a nice developer experience and optimizes your app for production You ll need to have Node gt and npm gt on your machine to use it npx create react app my appcd my appnpm startFrom the meme above it is clear that this method takes a long time to work So I recommend you to try vite They are way faster than normal methods I recommend you to watch this video to learn more Vite Crash Course day the first line most of the currently available and popular courses are not the latest version of React and if the course owner does not specify the easiest way is if he uses ReactDOM render JSX root not root render only JSX If you don t understand now it doesn t matter React versions Now let s start First open the HTML file you want react to work on and Add an empty lt div gt tag to mark the spot where you want to display something with React I prefer to use an empty lt main gt As if I will use React it will be for the whole site we will use an id To select this item and It is common to use words like app root main But you are free to choose any id lt main id app gt lt main gt If you use Npm way you will find Pre made files that contain everything you need to get started but with CDN links make sure you use the CDN script links make a new js file and linked to your html file Now it s really time for the first line Create a variable and link it to the element you create let container document querySelector app Create a variable and then link it with the first property in React which is createRoot and It is common to use words like react root mainRoot reactRoot pass container to createRoot const root ReactDOM createRoot container Wait a minute What is ReactDOM Why did we even do the above I Will explain to you What is ReactDOM Without complicated words ReactDOM provides you with the ability to manipulate the Dom Where in the previous example it was used to target one of the dom elements Why did we even do the above we determined what element React will work in the root And as the first use of this root What do you think about using React to create a new element inside root render lt h gt Hallo react lt h gt render used to render an element into the root we just create Did you notice anything strange here If you don t notice we just use html straight inside js and it will work Do you remember the link I told you to add without question for now yes jsx is responsible for this blessing but also today we will not talk about it This meme is enough for you to expect what it will doCongratulations you have used React for the first time If you do not understand any of the above and do not know how to create a variable at all perhaps programming really depends on intelligence kidding you just need to review js again And here unfortunately I must end the article I know that in terms of quantity I only talked about things that you can announce in the first quarter of an hour in any course but remember the purpose of this article is not to learn but to share with you the experience I went through while learning ConclusionThank you to anyone who reads this article I spent more time writing this article than I did learning React So I will stop writing for a bit and continue my journey with React But I promise to anyone who reads this article that I will complete the entire journey but the speed will depend on the amount of interaction In the end I would like to hear your opinions about the article What was missing Did you like the use of the meme in the article Should I add more or fewer details Do I add more explanation or cut it out and only talk about the experience Authorprofessional links twitter LinkedIn GitHubHire me UpWork FreelancerBlog hashNode dev to	2022-10-07 14:30:25

海外TECH	Engadget	The best midrange smartphones for 2022	https://www.engadget.com/the-engadget-guide-to-the-best-midrange-smartphones-120050366.html?src=rss	The best midrange smartphones for A great smartphone doesn t have to cost a fortune Years of commoditization have brought features once exclusive to high end devices including big batteries multi camera arrays and high refresh rate displays down to their more affordable siblings As one of Engadget s resident mobile geeks I ve reviewed dozens of midrange devices So I m here to help you figure out what features to prioritize when trying to find the best midrange phone for less than Engadget s picksBest midrange Android phone Google Pixel aBest and only iPhone under Apple iPhone SEMidrange phone with the best screen Samsung Galaxy A GUltra budget option OnePlus Nord N GWhat is a midrange phone anyway While the term shows up frequently in articles and videos there isn t an agreed upon definition for “midrange beyond a phone that isn t a flagship or an entry level option For this guide our recommendations for the best phone in this category cost between and Any less and you should expect significant compromises If your budget is higher though you should consider flagships like the Apple iPhone and Samsung Galaxy S What factors should you consider when buying a midrange smartphone Buying a new device can be intimidating but a few questions can help guide you through the process First what platform do you want to use If the answer is iOS that narrows your options down to exactly one phone Thankfully it s great And if you re an Android fan there s no shortage of compelling options Both platforms have their strengths so you shouldn t rule either out Obviously also consider how much you re comfortable spending Even spending more can get you a dramatically better product And manufacturers tend to support their more expensive devices for longer It s definitely worth buying something toward the top limit of what you can afford Having an idea of your priorities will help inform your budget Do you want a long battery life Do you value speedy performance above all else Or would you like the best possible cameras While they continue to improve every year midrange phones still involve some compromises and knowing what s important to you will make choosing one easier Lastly pay attention to wireless bands and network compatibility If you don t want to worry about that your best bet is to buy directly from your carrier To make things easier all the phones we recommend are compatible with every major US wireless provider and can be purchased unlocked nbsp What won t you get from a midrange smartphone Every year the line between midrange and flagship phones gets blurrier as more upmarket features trickle down When we first published this guide in it was difficult to find devices with waterproofing or G Now the biggest thing you might miss out on is wireless charging Just remember to budget for a power adapter too many companies have stopped including them Performance has improved in recent years but can still be hit or miss as most midrange phones use slower processors that can struggle with multitasking Thankfully their cameras have improved dramatically and you can typically expect at least a dual lens system on most handsets below The best midrange Android phone Pixel aSam Rutherford EngadgetThere s a lot to like about Google s Pixel a For one it features the best cameras at this price It may not have as many lenses as some of the other options on this list but thanks to Google s expertise in computational photography the a delivers pictures that are on par with phones that cost hundreds more Nighttime photos in particular are stellar thanks in part to Night Sight which helps brighten up dim environments and bring out more detail The Google Pixel a has a few other things going for it Thanks to its large battery and efficient chipset you won t have to worry about running out of juice It lasted just over hours in our battery testing and Google s Tensor chipset allows the a to run very similarly to the flagship Pixel and Pro handsets And those who plan to hang on to their smartphone for as long as possible will appreciate that Google plans to support the a with software updates for the next five years In addition to its solid battery life and performance the Google Pixel a even has some advanced features you may not expect to see on a midrange phone Its design looks very similar to the flagship models with the striking camera bar on the handset s rear top half and it has a x resolution OLED touchscreen with an under display fingerprint sensor You ll only get a refresh rate of Hz on the a but that s a small sacrifice to make when you re getting a number of other features at a killer price Buy Pixel a at Amazon The best and only iPhone under iPhone SECherlynn Low EngadgetIf you can get past its dated design and small inch display the Apple iPhone SE is the fastest phone you can buy for less than No other device on this list has a processor that comes close to the SE s A Bionic What s more you can expect Apple to support the model for years to come The company is only just ending support for the first generation SE after six years The company hasn t said how long it intends to furnish the latest SE with new software but it s likely to support the device for a similar length of time For all its strengths the iPhone SE is held back by a dated display Not only is the SE s screen small and slow but it also uses an IPS panel instead of an OLED meaning it can t deliver deep blacks Additionally that screen is surrounded by some of the largest bezels you ll find on a modern phone That s not surprising The SE uses the design of the iPhone which will be a decade old in two years And if the SE looks dated now it will only feel more tired in a few years Shop iPhone SE at AppleThe midrange phone with the best screen Samsung Galaxy A GIgor Bonifacic EngadgetFor the best possible display at this price look no further than Samsung s Galaxy A G It features a inch Super AMOLED display that is ideal for watching TV shows and movies Plus the Hz panel is the fastest on this list Other standout features include a mAh battery and versatile camera system The A s three cameras may not deliver photos with the same detail and natural colors as the Pixel a but it can capture bigger scenes with its two wide angle lenses Like the other Android smartphones on this list the Samsung Galaxy A isn t the fastest performer At best Samsung s Exynos is a lateral move from the Snapdragon G found in the Galaxy A G And though the A is cheaper than its predecessor it no longer comes with a power adapter and headphone jack so the difference may not end up being much Buy Galaxy A G at Samsung An ultra budget G option OnePlus Nord N GBrian Oh EngadgetIf you only have around to spend on your next phone you could do a lot worse than the OnePlus Nord N To start it features a big mAh battery that will easily last you a full day The N also has a Hz display and G connectivity which are tricky to find at this price Best of all it doesn t look like a cheap phone But the N is also a good illustration of why you should spend more if you can It s the slowest device on this list due to its Snapdragon chipset and paltry GB of RAM Its triple main camera system is serviceable during the day but struggles in low light and doesn t offer much versatility beyond a disappointing macro lens OnePlus also doesn t plan to update the phone beyond the soon to be outdated Android In short the N is unlikely to last you as long as any of the other recommendations on this list Buy OnePlus Nord N at Amazon Chris
