jQuery is a free, cross-platform JavaScript library created to facilitate client-side scripting in the HTML code of web2 pages. The first version was released in January 2006 by John Resig. Since the purpose of the library is to browse and modify the DOM (including support for CSS selectors 1 to 3 and basic XPath support), it contains a lot of features; including animations, handling of cascading style sheets (accessibility of classes and attributes), event management, etc. The use of Ajax is facilitated and many plugins are present. Since its creation in 2006 and in particular because of the growing complexity of Web interfaces, jQuery has been very successful with Web developers and its training is today one of the fundamentals of training in Web technologies. It is currently the most used front-end library in the world (more than half of online websites integrate jQuery). However, its use becomes less relevant with the emergence of new libraries such as React (JavaScript) and Vue.js which replace it in the construction of Single-page Web Application.
