This article introduces the relevant knowledge of "what are the main applications of javascript". In the operation of actual cases, many people will encounter such a dilemma. Next, let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Javascript main application aspects: 1, website front-end development; 2, server development; 3, command line tool development; 4, desktop application development; 5, mobile development (Web app, hybrid application development); 6, plug-in development; 7, game development, etc.

The operating environment of this tutorial: windows7 system, javascript1.8.5 version, Dell G3 computer.

JavaScript, referred to as JS, is a client scripting language, which is mainly used to add a variety of dynamic functions to HTML pages to provide users with a more smooth and beautiful browsing effect. Can be directly embedded in HTML pages, but written as a separate js file is conducive to the separation of structure and behavior, in the vast majority of browsers support, can run in a variety of platforms (such as Windows, Linux, Mac, Android, iOS, etc.), JS mainly runs on the client side (browser), can also run on the server side (operating system).

Main application aspects of javascript (scenarios):

1. Website front-end development

Javascript's old job. Used to implement front-end logic, such as what happens when you click a button.

2. Server-side development

Node.js gives programmers the freedom to write the back end with js.

3. Command line tool development (Node.js)

4. Desktop application development

It mainly means that browsers such as chrome can package programs written by js into desktop applications. Chrome OS pushed by Google is also an operating system based on web app.

5. Mobile development

1), Web app

HTML5 provides a lot of API support to implement most of the functions of native applications, but performance needs to be improved. For example, Firefox OS is a mobile operating system based on web app.

2), hybrid application development

Part of the native application is implemented with the front-end technology to make the native application more flexible. Many apps do this. The emergence of platforms such as PhoneGap allows programmers to use js for mobile application development.

6. Plug-in development

Javascript is the only programming language that is natively supported on all major platforms, so js can be used for plug-in development on all major platforms. Browser plug-ins and extensions are common, and plug-in platforms for most mobile applications are also developed using js, because one development can guarantee cross-platform use.

7. Game development (cocos2d-js)
