3 Reason Why Javascript Should be your First Language |
https://dev.to/kinjiru09/3-reason-why-javascript-should-be-your-first-language-22jo
|
Reason Why Javascript Should be your First LanguageThere are many languages to choose as your first language i e Python JavaScript Go and Ruby All these languages have been heralded as easy languages to learn There are good reasons to call these languages “easy They are easy to set up and relatively easy to start creating projects They have easy syntax and concepts that a beginner would find easy to understand right away They have vibrant communities around them There are a ton of libraries to help you build robust programs There are many tutorials books videos courses and other resources to learn these languages Another reason to learn one of these languages is there are many companies looking for developers who know these languages and they are willing to pay a decent wage For example the average JavaScript developer with experience can make over But which one of these languages should be your first language There are three reasons why Javascript should be your first language LanguageThe actual Javascript language ignoring the platform i e browser or Nodejs has been a matter of controversy for years Many people love it others hate it It is a widely used language with a long history But the language has gone through so many revisions that now we are stuck in this hybrid state where some developers write JavaScript one way and other developers write it another way This could be very intimidating and down right annoying at times But in reality it created a world where a developer can learn how to code in different mindsets JavaScript is a multi paradigm scripting language It supports object oriented imperative and functional programming styles Even though it s a dynamic language you can use strongly typed languages that are built on top of JavaScript like Typescript The flexibility of the language allows you to write in all these different paradigms Mastering these paradigms can benefit you later on when you want to learn another language that emphasizes one of these paradigms i e an object oriented language PlatformJavaScript started in the web browser It s one of the core technologies of the web Learning JavaScript allows you to understand how the web works The amazing thing about Javascript is you literally have access to thousands and thousands of websites at your fingertips That means you have access to all these websites Javascript code You can read other people s code learn and practice Getting started with JavaScript is relatively easy Open a browser and start playing with code in the console or open up any text editor and start writing some code inside of html tags and then open the file in your browser no setup required Now JavaScript engines are common components of both server side website deployments and non browser applications With the creation of Nodejs React Native Cordova Electron and other application frameworks you can build mobile applications desktop applications games and server side applications and services JavaScript has even appeared in some embedded systems To be honest though depending on your requirements and needs JavaScript may not always be the best solution for non website apps The fact that you can learn JavaScript and transfer that knowledge to a different platform is very powerful and a great incentive for learning the language Even though many languages like Python can be used across different platforms Javascript still dominates the web Concepts amp Design PatternsThe third reason why you should learn JavaScript is that there are concepts and design patterns that are openly exposed to you while learning the language on different platforms For example if you write server side JavaScript using Nodejs you are introduced to principles and design patterns that are at the core of the Nodejs ecosystem For example you will learn the following concepts and design patterns ModulesEvent LoopCallbacksEvent Emitter ModulesThe concept of modules teaches you how to structure your code in small well defined components Each module should focus on one thing and it should do it well This helps you keep your code simple and understandable This also helps with testing This concept is seen throughout all of Nodejs APIs This is good training for new developers Event LoopWhen you learn about Nodejs asynchronous nature and it s Event Loop you are actually seeing the reactor pattern in use This design pattern is an event handling pattern Each I O operation event i e file access network operation etc is associated with a handler see callbacks below When an operation is done its result is passed to the handler and the handler is invoked The event loop handles all of this CallbacksBecause of Nodejs asynchronous nature it uses a unique design pattern at its core called the callback pattern When an operation is done it sends the result to another function This pattern has pros and cons But you are exposed to another design pattern so it is still good for new developers to see how design patterns are used Event EmitterThe event emitter class is at the core of Nodejs This shows the observer pattern in use An object can notify listeners when its state changes i e when a button is clicked when user input text in a text box etc This is a common design pattern used in many programming frameworks and platforms Seeing how it is used in a production grade framework like Nodejs is good training for new developers Every platform has its own pros and cons and design principles These are just a few I wanted to mention that are associated with Nodejs TLDR Javascript is used in many places and it can be fun to write and use in personal projects as well as professional projects After learning JavaScript you can definitely find a developer job to get experience as a developer Then you can learn other languages to advance your career |

When should I use asynchronous code in JavaScript? |
https://dev.to/nicozerpa/when-should-i-use-asynchronous-code-in-javascript-1kfk
|
When should I use asynchronous code in JavaScript If you were learning JavaScript for some time I m sure that you ve heard about asynchronous code Promises callbacks the async and await keywords etc But a question that often gets unanswered is when should I even use asynchronicity The short answer is only if you have to use a function that is already asynchronous and you need the return value of that function For example imagine that we have to create a function that receives the number of a Pokémon and returns its name e g if you pass the number it returns Pikachu In this function we ll call the PokéAPI using the native fetch function The thing is fetch is an asynchronous function And we need what this function returns because it s the response from the API It means that the function we create should be asynchronous use strict Enable strict modeasync function getPokemonName pokemonNumber let pokeApiResponse await fetch pokemonNumber pokeApiResponse await pokeApiResponse json return pokeApiResponse name const pokemon await getPokemonName console log Pokémon is pokemon Prints Pokémon is pikachu In some cases however you can choose whether to use synchronous or asynchronous functions to perform the same task This often happens in Node js where you can read and write files using synchronous functions or asynchronous ones Which ones should I use If you re creating the back end of a website using Node js or Deno or you re working on the front end you should definitely use the async versions Synchronous tasks block everything else It means that if a task takes a lot of time in Node other people won t be able to enter the website until that task finished On the front end the site will freeze while a synchronous task runs That s why async works better in those cases If you liked this article you ll love my JavaScript Newsletter Every other Monday I ll send you easy and actionable steps to level up your JavaScript skills Check it out |

Analogue Pocket first look: Handheld gaming as good as it ever was |
https://www.engadget.com/analogue-pocket-first-look-handheld-gaming-as-good-as-it-ever-was-160050430.html?src=rss
|
Analogue Pocket first look Handheld gaming as good as it ever wasFar too long ago for our impatient souls boutique console maker Analogue teased something exciting A retro handheld that mimicked multiple classic systems including All the Game Boys the Sega Game Gear the Neo Geo Pocket and the Atari Lynx Oh and more recently announced the TurboExpress too In other good news Analogue also just announced that orders for the Pocket will open again on December th tomorrow The slightly less good news is that at it ll cost more than originally planned but you can blame the virus for that and its impact on supply chains Finally it s here and it s…still just as exciting So much so that the short time I ve had with the Pocket isn t enough to give it the deep dive review it deserves You have to remember this thing not only plays old games from original cartridges It does so using a party trick called field programmable gate arrays or FPGA All you need to know is that FPGAs effectively mimic old consoles at the hardware level When you plug in a game it thinks it s in an original Game Boy or whichever system for the relevant adapter you might be using Couple that with a display custom designed to replicate vintage screens quirks and all and this has all the ingredients to be the most authentic retro handheld you can find Our early testing with Game Boy original and Game Boy Advance games indicates this really is one of the most authentic experiences you can find Pretty much the moment you pick this thing up you know you re in for a treat If the original Game Boy had been released today with a Scandinavian design this is what it would look like The clean lines and monochrome aesthetic tell you this is all about the game there are no garish colors of cliche nods to the s here Just one dash of color on the left hand side for the power button and that s as flashy as things get The general layout broadly matches the first gen and Game Boy color with the screen up top and controls underneath Though there are four thumb buttons instead of two as you ll be able to create games for this yourself either with GB Studio or via the spare FPGA core Analogue added just for developers There are shoulder buttons too as per the Game Boy advance Fortunately the display is thoroughly modern and not like the squinty if much loved one from back in It s also handily times the resolution on both axes so it can serve up pixel perfect renditions of your favorite original Game Boy titles The way it reproduces original Game Boy games is quite remarkable Turn the Pocket on and the minimalist interface leads you straight to the good stuff Playing games I won t lie firing up Tetris for the first time and changing the Pockets display mode to the original green and black game boy mode was quite the dash of nostalgia I ve played Game Boy games on several “modern handhelds and none of them looked like this Even the pixel grid of the original is here the motion blur if you want it the sound Everything felt just as it did all those years ago The same goes for Game Boy Advance games If you ever owned the first model of GBA you ll painfully remember that it still didn t have a lit screen The Pocket does but everything else matches including a preset for that slight washed out look that comes with just colors on a non illuminated LCD You can of course choose a more modern display mode if you like but purists are going to love the attention to detail here The authenticity doesn t stop at the fidelity of the games The “link port on the Pocket happens to be the same as the one found on the Game Boy Color and onwards That means if you have the original hardware or another Pocket you can play with friends just like you would have back in the proverbial day I do have the original hardware and we re testing those features right now which you ll see in our full review In terms of compatibility so far the only glitch we ve had is with a very unofficial Game Boy Advance multicart everything else has worked a charm ーincluding fund stuff like the Game Boy Camera The same goes for Game Gear titles which is the only other platform we can try right now There s so much more to cover here we kinda can t wait to show you it all There s the dock accessory for playing on a TV with real controllers there s the aforementioned music making app there s Analogue s own operating system which hides more than a few perks and then there are the adapters for all the other consoles For now we re excited to say that the Pocket appears to deliver on its key promises The hardware feels fantastic and we keep going back for more Tetris even when it s way past our bedtime You ll just have to wait a few more days for our comprehensive review |
