Web front-end development why to learn JS, I believe that many inexperienced people do not know what to do, so this paper summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

In the front-end world, there is nothing JavaScript can not achieve, there is a saying about JS: all applications that can be written in JavaScript will eventually be run in JavaScript,JavaScript on all major browsers on all major platforms, or on the server side of every major operating system. Nowadays, when we write any major function for the website, we need a developer who can write the front end in JavaScript.

It doesn't matter what the back-end code is written in-- whether it's Java,PHP,.NET,Node.js or otherwise-- but the client must need a JavaScript developer. In fact, many developers still don't realize how powerful JavaScript is.

Web front-end development, the need to master the programming language JavaScript, what are the functions and areas of JS? 1. Data visualization

Data visualization is a popular interactive display mode, while Java has a variety of frameworks to achieve data visualization, such as ECharts, Dygraphs.js, D3.js, InfoVis, Springy.js and so on.

two。 Mobile application

PhoneGap brings WebView to mobile apps as well as JavaScript to mobile apps.

3. Server side

Because the performance of V8 brings JavaScript to a new level, Node.js was born-both front-end and background can use JavaScript, and now any web page can't do without JavaScript.

4. Full platform application

A piece of code to build mobile, desktop, Web can be used all over the platform, and running Ionic on Eletcron means unlimited possibilities.

5. Games

If you only stay in the era of Flash for online games, it would be wrong to think that only Flash can make very gorgeous game special effects. JavaScript can also make gorgeous special effects!

6.VR

With 3D game engines such as Three.js, you can also create a 3D world.

7. Hardware

Tessel can run JavaScript directly on the device, without the need for a server, and then develop it like a web developer by using IDE and libraries to upload new firmware with a tessel push instruction.

8. Operating system

So is it possible to create an operating system using only Node.js? NodeOS will learn that although it uses the Linux kernel to handle various low-level tasks, such as hardware communications, Node.js is used other than that.

The position of JavaScript in the whole WEB: it belongs to the core of the front end, which is mainly used to manipulate and readjust DOM, and to modify the page effect by modifying the structure of DOM.

After reading the above, do you understand why Web front-end developers still need to learn JS methods? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
