PopularJavascript LibrarySuch as jquery, mootools, prototype, dojo, and Yui. These JS libraries provide many ready-made functions for client actions (events), animation effects (effects), and Ajax applications. In addition, if one of these libraries cannot directly achieve the desired effect, there may be related plug-ins that meet your requirements.

The flexibility of the Javascript Library provides convenience for our work, but it also has advantages and disadvantages-for example, the Javascript file is too large.
