Why do you think jquery is not easy to use? Brief analysis of the reasons

With the continuous development of front-end technology, the jQuery framework is no longer the best choice at present, not only because modern browsers already have most of the functions of jQuery, but also because other more advanced frameworks such as React or Angular development of front-end pages can achieve code reuse more efficiently.

However, jQuery, as an early web development framework, was once an indispensable tool for front-end developers. With its simplicity, convenience and good compatibility, jQuery helps front-end developers quickly build browser-compatible dynamic web pages.

Although jQuery saves us a lot of time and code, there are also many people on the Internet who criticize jQuery for not being easy to use. Many of these criticisms stem from a lack of deep understanding of the nature of jQuery. When using jQuery, we need to understand the principles behind it, not just simply call its API. Here are some reasons that may cause some developers to criticize jQuery:

1. All functionality is contained in one large JS file

jQuery basically covers all front-end development needs , such as DOM operations, event handling, animation, AJAX, etc. However, since it has corresponding methods and events for each function, its JS file is very large, which will increase page loading speed and file download time.

2. Easy to be replaced by other frameworks

jQuery's simplicity, ease of use and scalability were difficult for other developers to replace it in the early days of its release. But with the emergence of other more mature, powerful, and actively maintained frameworks on the market, such as React and Angular, jQuery's price/performance ratio has become very low.

3. No support for future standards

Although jQuery provides a perfect solution for solving legacy browser compatibility, it does not fully support future browser standards. . HTML 5, as a standard, includes many new properties and methods that are not well supported in jQuery.

Despite these shortcomings, jQuery is still one of the indispensable front-end development frameworks for many developers and most enterprises. Both those in the early stages of development and those who want to maintain the integrity and compatibility of older projects can benefit from jQuery.

In addition, as the version of jQuery continues to be upgraded, it is also improving to solve the above shortcomings. The latest version of jQuery, jQuery 3.4, has started to use ES6 language elements and has also rewritten the API to improve performance.

To summarize, although jQuery’s current position in the front-end development framework market is not what it used to be, it is still a valuable tool, especially for those who need to solve compatibility issues with older browsers. At the same time, if you plan to learn more efficient frameworks such as React or Angular, you must first have a deep understanding of jQuery's API and principles, as this will help you better understand and master the application of these frameworks.
