jQuery simplifies the process of selecting and manipulating HTML elements in the Document Object Model (DOM). It provides a concise syntax for traversing and modifying the structure and content of a web page, such as adding or removing elements, changing styles, or updating text.
jQuery has a vast ecosystem of plugins and user interface (UI) components that can be easily integrated into web projects. These plugins offer additional functionality, such as image sliders, form validation, date pickers, tooltips, and more. They enable developers to extend the capabilities of a website without having to build everything from scratch.
