What's good about jquery

With the continuous advancement of Internet technology, front-end development has been regarded as an important part of the development of Web technology. As one of the most important tools in front-end development, jQuery is more simplified and efficient than native JavaScript and is widely used in development.

So, what’s so good about jQuery?

1. Unique selector makes developers more convenient

Compared with native JavaScript, jQuery has a more powerful and smart selector function. Only a $ sign plus a selector is needed to reference the element, so you don't have to worry about misoperations caused by the same element name. There are many types of selectors. In addition to the basic id and class selectors, there are also attribute, sub-element, pseudo-class selectors, etc., which are very flexible to use. Moreover, jQuery can use CSS3 selector specifications to make selecting elements easier and faster.

2. Rich API, powerful functions

In addition to selectors, jQuery also provides a very rich and powerful API. Its API can help developers easily complete development work such as event binding, obtaining DOM element information, dynamically adding, deleting, modifying nodes, animation effects, etc. Compared with native JavaScript, it reduces the amount and complexity of developers' code, greatly improves development efficiency, and allows developers to focus more on business issues rather than DOM operation issues.

3. Strong compatibility, more assured development

With the continuous development of Web technology, different browsers have different restrictions on supporting certain Web standards. This Often becomes a big problem for front-end developers. jQuery is like an adapter, it can automatically adapt between different browser platforms, ensuring consistency and compatibility on various browsers. This means that developers do not need to consider the compatibility of other platforms and focus more on the implementation of business logic.

4. The development community is active and the ecosystem is complete

jQuery has strong community support. Developers can easily find some excellent open source plug-ins and programs, all of which are developed by Written and shared by passionate developers. These plug-ins allow developers to quickly expand functionality during the development process without having to write repeated code.

5. Superior performance and doubled efficiency

In order to optimize performance, jQuery uses a variety of strategies to minimize the number of DOM operations, such as object caching mechanism and chain calls. This can greatly improve performance and efficiency, allowing developers to develop efficient web applications faster.

In summary, jQuery is simple, efficient, easy to use, highly compatible, and has a strong development community, excellent ecology, and rich APIs, all of which make it indispensable in front-end development. One of the tools. This is why more and more developers trust and use jQuery.
