This article mainly introduces the advantages of jQuery, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

JQuery is a cross-browser open source JavaScript library whose core philosophy is write less, do more (write less, do more). Through the encapsulation of JavaScript code, the implementation code of DOM, event handling, animation effect Ajax and other functions is more concise, and effectively improve the efficiency of program development.

JQuery was first officially released by John Resig in January 2006 and has attracted the attention of many JavaScript experts from all over the world. There are many JavaScript libraries born with jQuery, such as Prototype, ExtJS, Mootools, YUI and so on. Among the many JavaScript libraries, why is jQuery favored by so many Web developers? This is mainly due to the following advantages of jQuery.

Lightweight package: jQuery is a lightweight script whose code is so small that the production version has a package size of only 94.8 KB.

Concise grammar: the grammar is concise and easy to understand, and the learning speed is fast.

Comprehensive documentation: jQuery documentation is very comprehensive, easy for developers to use.

Powerful selector: supports attributes and selectors defined by CSS1--CSS3, and the way to get elements is more flexible than native JavaScript.

Excellent cross-browser compatibility: jQuery solves the problem of cross-browser compatibility in JavaScript. Supported browsers include IE6--IE11, Firefox, Chrome and so on.

Separation of script and tag: separation of JavaScript code and HTML code is realized in jQuery, which is convenient for code management and later maintenance.

Rich plug-ins: jQuery has many mature plug-ins, such as form validation plug-ins, UI plug-ins, etc. Developers can extend more functions through plug-ins.

At present, jQuery has released three series of versions, namely jQuery 1.x, jQuery 2.x and jQuery 3.x. The characteristics of each series of versions are as follows.

JQuery 1.x: compatible with IE6/7/8, it is the most widely used. At present, it is only maintained by Bug and no other functions are added. For projects with non-special requirements, use the jQuery 1.x series version. The latest version of jQuery 1.x is 1.12.4 (released on May 20, 2016).

JQuery 2.x: not compatible with IE6/7/8, because it does not support low-end IE browsers, the current number of users is small. Similarly, officials only do Bug maintenance, and no other functions are added. If you do not consider compatibility with older browsers, you can use the jQuery 2.x series version. The latest version of jQuery 2.x is 2.2.4 (released on May 20, 2016).

JQuery 3.x: not compatible with IE6/7/8, only the latest browsers are supported. Because many of the more mature jQuey plug-ins do not support the jQuery 3.x version, the jQuery 3.x series version is not commonly used. Currently, jQuery 3.x is the official major updated and maintained version.
