Basic concepts of jQuery with advanced programming

(1) jQuery is an JavaScript library created by American John Resig in 2006, which developed from the original version 1.0 to version 1.5.2 released in March 2011. As an JavaScript library, jQuery solves browser compatibility problems for the most part and works with IE 6.0 +, FF 2.0 +, Safari 3.0 +, Opera 9.0 +, and Chrome.

(2) Although jQuery is not the only JavaScript library, nor is it the earliest JavaScript library, jQuery is the most influential. It continues to attract technical enthusiasts and experts from all over the world to join its ranks, and has almost become the DE facto standard in the field of Web development. Today, even an JavaScript engineer who insists that he does not want to use jQuery must be able to understand the jQuery code, or else he cannot easily communicate and collaborate with others. As a result, jQuery has become a basic skill for front-end development practitioners.

(3) In theory, jQuery is just a set of code based on JavaScript, and its capability cannot exceed JavaScript. Even some functions still depend on JavaScript itself. While many people may take it for granted that learning to use JavaScript is enough, jQuery should be left to the opportunistic. However, it turns out that jQuery is not optional. The emergence of jQuery completely liberates the creativity of developers, enabling a large number of excellent web applications to spring up in a dizzyingly rapid pace, creating a prosperous situation that the original JavaScript failed to achieve.

(4) In order to experience the practical application of jQuery up close, readers can visit the following foreign websites. One of the common features of these gorgeous websites is that they all use jQuery to create rich interactive elements and dynamic effects on the web.

(5) jQuery isn't just a beginner's best choice. It's already in use in the world's largest organizations, enhancing the interactivity of hundreds of millions of page views every month. A large number of companies, including Amazon, IBM, Twitter, NBC, Best Buy and Dell, use jQuery in their products.

(6) According to the development law of Web, there is no doubt that jQuery will evolve rapidly at the development speed of Web. At least three major VERSIONS of jQuery were released in 2011, and the development community around jQuery continues to grow, with developers around the world contributing significantly to jQuery's bug revisions, 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 adopted, jQuery has outstanding features in the front-end development field for various Web technologies such as Java/Spring, PHP,.ES69en, Ruby on Rails and Python/Django.
