(2) Although jQuery is not the only JavaScript library or the earliest JavaScript library, jQuery has the greatest influence, it constantly attracts global technical enthusiasts and experts to join the camp, and has almost become a de facto standard in the Web development field. Today, even JavaScript engineers who insist on not using jQuery must be able to understand jQuery code; otherwise, they cannot easily communicate and cooperate with others. Therefore, jQuery has become a basic skill for front-end developers.

(3) In theory, jQuery is just a set of code built based on JavaScript. It cannot exceed JavaScript, and even some functions still rely on JavaScript. Maybe many people take it for granted that learning to use JavaScript is enough. jQuery should be reserved for opportunistic people. However, it turns out that jQuery is not dispensable. Its emergence has completely liberated developers' creativity and led to the explosive emergence of a large number of excellent network applications, it can be said that it created a prosperous situation where JavaScript was not previously achieved.

(6) according to the Web development rules, there is no doubt that jQuery will evolve rapidly at the pace of Web development. In 2011, at least three major jQuery versions were released, and the development community around jQuery continued to grow, developers all over the world have made important contributions to jQuery's bug fixes, plug-in development, and related jQuery UI and QUnit projects. For anyone who wants to engage in world-class JavaScript development, the active jQuery technology community ensures that jQuery becomes a fully functional JavaScript library.

(7) Conclusion: No matter which programming methodology or programming technology is used, for Java/Spring, PHP ,. NET, Ruby on Rails, Python/Django, and other Web technologies. jQuery has outstanding features in the front-end development field.
