Introduction to jquery (i)

Summary: A brief introduction to the origins of jquery and why you need to use jquery.

　　The benefits of jquery

With its small volume and fast loading, jquery has its own features that make it easy for JavaScript application developers to work. The biggest highlight is the excellent DOM query tool, which uses the well-known CSS selector syntax.

　　Features of jquery

The goal of jquery is to "write less, do more," and jquery makes cross-browser web development simple and seamless. The performance of jquery is excellent in the following areas:

1, through a variety of built-in methods, more convenient to use jquery to iterate and traverse the DOM;

2. jquery provides a high-level, built-in, general-purpose use of selectors, as in CSS, so it's easier to use jquery to select entries from the DOM;

3. jquery provides an easy-to-understand plugin architecture that allows you to add custom methods;

4. jquery helps reduce the redundancy of navigation and UI features, such as tabs (tab), CSS, markup-based pop-up dialogs, animations, transitions, and many other effects.
