Why use jquery

jquery is a very popular JavaScript library that simplifies many common tasks in JavaScript development. jquery provides an easy-to-use API that enables developers to quickly build interactive and dynamic web applications.

In the early days of web development, developers needed to write complex JavaScript code themselves to implement many common tasks, such as DOM operations, event handling, animation effects, AJAX requests, etc. However, due to differences in browsers and limitations of the JavaScript language itself, these codes often need to consider many details, making development very cumbersome and time-consuming.

With the advent of jQuery, developers can handle all these basic tasks using the simple yet powerful API provided by jquery. jQuery encapsulates many common DOM operations, such as adding, removing, and modifying HTML elements, as well as setting styles and attributes of elements. It also provides a set of event handling mechanisms, allowing developers to use a simple way to bind and handle various events, such as clicks, mouse movements, keyboard input, etc.

In addition, jquery also provides many built-in animation effects, such as fade, slide, zoom, etc., allowing developers to easily apply these effects to enhance the user experience of web applications. jquery also provides a set of AJAX APIs that allow developers to easily use JavaScript for server-side communication to achieve data interaction without page refresh.

Another advantage of jquery is its cross-browser compatibility. It works well in all major browsers, including Internet Explorer 6 and above, Mozilla Firefox, Google Chrome, Safari, and more. This compatibility saves developers a lot of time and effort from writing separate code for different browsers.

Finally, the use of jquery also helps improve development efficiency. Because the API it provides is simple and easy to use, developers can implement functions more quickly and reduce the chance of errors. In addition, jquery has many third-party plug-ins and tools that can be used to further enhance its functionality, such as jQuery UI for building user interfaces, jQuery Mobile for building mobile applications, jQuery DataTables for building data tables, etc.

In general, the use of jquery has many benefits. It can simplify the development process, improve development efficiency, enhance the user experience of the application, improve the readability and maintainability of the code, etc. Therefore, jquery, as a popular JavaScript library, has been widely used and supported.
