With the continuous development of web development, front-end technology has also developed rapidly. Among them, jquery, as an excellent javascript library, has influenced countless front-end developers. The convenience, readability and compatibility of jquery make it an indispensable part of many front-end development. However, the version of jquery is also constantly updated, so the introduction of different versions of jquery will be helpful to many developers.
- jquery1.x
jquery1.x is an earlier version of jquery and is mainly compatible with old browsers, including ie6, ie7 and other browsers. If you need to be compatible with IE6 and above browsers, you can choose to use jquery1.x.
- jquery2.x
jquery2.x is a later version of jquery. It mainly abandons compatibility with lower version browsers, reduces file size, and improves performance. In addition, jquery2.x also removes support for some features that are no longer supported, making the code more concise, clear and standardized.
- jquery3.x
jquery3.x is the latest version of jquery, supports all modern browsers and is no longer compatible with older browsers, which means more can be used HTML5 and CSS3 features. In jquery3.x, some methods have been optimized and performance has been improved. In addition, jquery3.x also completely removes some methods and features that were deprecated in earlier versions.
