Has jquery been abandoned?

jquery has not been abandoned. Although it is outdated, it has not been abandoned. The reasons are: 1. Most of the websites and applications on the market are still based on jQuery. In the next few years, there is still a need for Maintenance with jQuery; 2. Many companies do not have full-time front-end development, and their front-end work is handled by the backend. These people prefer the working mode of using jQuery plus backend templates; 3. IE678 has not disappeared, so jQuery still has its place; 4 , jquery is easy to use and is very suitable for making some simple websites.

Has jquery been abandoned?

jquery has not been abandoned. Although it is outdated, it has not been abandoned.

1. What pain points has jQuery solved?

When discussing whether a library or framework is outdated, you should first look at what problems it solved and whether these problems are better now. s solution.

What problems does jQuery solve?

Browser compatibility issues

In the era when IE678 was rampant, browser compatibility issues were a skill that front-end partners must master. What kind of bugs did IE6 have? IE does not recognize any standard JavaScript methods and objects. You have to remember this. When writing ajax, others use XMLHttpRequest, but when it comes to IE, you have to use ActiveXObject. The hard-working front-end programmers cannot concentrate on researching technology and can only wipe their butts for browser manufacturers every day. Until the emergence of jQuery, everyone was relieved. Whether it was DOM manipulation, event binding, or ajax, jQuery encapsulated methods compatible with various browsers for us, and it felt like the whole world was at peace.

Selector

Without jQuery, we have to use getElementById and getElementsByTagName to obtain the DOM object. Bind events to all elements of the list, either by event delegation or by traversing all elements. In order to deal with the damn DOM interface, we have mastered all kinds of weird techniques, but they are actually useless. With jQuery, we can use css selectors to obtain elements, and binding events no longer requires traversing the element list, which makes everyone feel refreshed.

Animation Effect

I clearly remember the first time I used a timer to write animation, how to make an element move, and how to stop it from moving. After debugging, there are no bugs. This requires a lot of code, let alone creating a complete page effect. Just thinking about it makes people collapse. Looking at the animation effects that jQuery provides us, we simply can’t imagine how we can achieve the effects we want in IE678 without jQuery.

Summary

jQuery solves far more pain points than these: its DOM operations, style operations, attribute operations, event binding, as well as traversal and form serialization , ajax packaging, these functions bring a new world to front-end development. To this day, jQuery is still the most used library by front-end developers, no one!

2. Solutions to replace jQuery

jQuery’s impact on the front-end is unprecedented, but with the development of the front-end, jQuery has also entered an obsolete era status, and the pain points it solves for us already have alternatives.

Browser compatibility

The problem of browser compatibility is becoming less and less of a problem. IE6 can be said to have been eliminated (currently only large state-owned enterprises, institutions, and government agencies) There are also XP systems in hospitals that still retain IE6, but are starting to be phased out). Tmall announced last year that it would no longer support IE8. Although browser compatibility issues still exist, it is no longer the era of overwhelming problems.

Selectors

CSS3 has added a large number of selectors and operation styles. You can find them wherever you want without having to bother with jQuery.

Native JavaScript also adds querySelector and querySelectorAll methods, which can directly obtain elements through css selectors.

Animation effects

css3 provides rich transition and animation effects, allowing us to no longer rely on jQuery.

ajax

Third-party modules such as fetch and axios have encapsulated ajax quite well. We no longer need to introduce jQuery just for a $.ajax.

DOM operation and event binding

Putting aside the issue of animation, the rest is mainly the addition, deletion and modification of data. This kind of operation uses jQuery, regardless of the performance point of view , or from the perspective of ease of development and maintenance, the mvvm framework is much better than jQuery.

Componentization and modularization

Componentization and modular development are the mainstream of front-end development now. The advantages are simply easy to develop, easy to maintain, and easy for the team. Division of labor.

jQuery can be developed in components, but writing components with jQuery can be described in two words: it hurts, whoever uses it will know.

Modularization, whether it is using ES2015 (import, export) or webpack (require, module.exports), if not, we will use require.js or sea.js in retrospect, which is obviously the same as jQuery has nothing to do with it

To sum up

All the advantages of jQuery have better solutions. It can be said with certainty that jQuery is outdated!

(If your company requires compatibility with IE678, that is a different matter.)

##3. jQuery has not been abandoned

Most websites and applications on the market today are still based on jQuery. In the next few years, they will still need to be maintained with jQuery.
• Many companies do not have full-time front-end developers, and their front-end work is handled by the backend. These people prefer to use jQuery plus backend templates.
• Some front-end developers with more than two or three years of work experience are content with the status quo, reject the new features of CSS3, and have no patience to learn the mvvm framework. jQuery is still their main tool.
• IE678 has not disappeared, so jQuery still has its place.
• jQuery is easy to use and is still suitable for making some simple websites.
