What is jQuery?
jQuery allowed users to select DOM elements using CSS selector syntax, offering a smooth and consistent surface for running DOM manipulations, AJAX requests, and animations. The ease of use, cross-browser compatibility, and neat syntax quickly made jQuery a popular language of choice for most front-end developers. It surged in popularity past existing libraries, such as Scriptaculous, Prototype, and Mootools.
Changes That Affected jQuery
However, even as jQuery gradually lost its grounds, the library is still relevant. This is because the new technologies were frameworks and not libraries. jQuery was a library, which is simply a collection of functions. On the other hand, new developments, such as Angular JS, were programming frameworks. As such, their use cases never overlapped each other completely.
Should You Learn or Use jQuery?
It is important that you choose the right tools and technology when working in the web development realm. This involves your choice of a programming language, framework, and library. Therefore, despite the declining popularity, jQuery is an amazing library with elegant chaining methods. You should consider using jQuery when working with simple WordPress websites with fewer interactions when developing a website or apps targeting old browsers, or working with plugins that depend on jQuery. That said, if you decide to learn jQuery, consider taking an online course. In some cases, financial aid may be available to you. For example, a number of online coding courses accept G.I Bill benefits.
