As of may additionally 2019, jQuery is utilized by seventy-three% of the ten million maximum popular websites. web evaluation shows that it's far the maximum broadly deployed JavaScript library by means of a big margin, having as a minimum three to four times greater usage than another JavaScript library. jQuery's syntax is designed to make it simpler to navigate a file, pick out DOM factors, create animations, take care of activities, and expand Ajax packages. jQuery additionally gives skills for builders to create plug-ins on top of the JavaScript library. This allows builders to create abstractions for low-stage interplay and animation, superior outcomes, and high-level, themeable widgets. The modular approach to the jQuery library allows the introduction of effective dynamic internet pages and internet applications.

The set of jQuery center features—DOM detail picks, traversal and manipulation—enabled with the aid of its selector engine, created a brand new "programming fashion", fusing algorithms and DOM information systems. This fashion prompted the architecture of other JavaScript frameworks like YUI v3 and Dojo, later stimulating the introduction of the usual Selectors API.
