jQuery

jQuery is the most popular JavaScript library designed to simplify the client-side scripting of HTML that has many visual functions such as document traversing, event handling, animating, and Ajax interactions for rapid web development.

jQuery plugins can simplify the work of designers as they only have to customize certain parts of the jQuery plugin that they've used to match the designs they are doing. jQuery is easy to use and understand and it does not require advanced programming skills. Even the most amateur designers and developers can learn how to use it in no time thanks to its simplicity that takes away most of the tedium that usually goes along with coding. jQuery helps to speed the web design process up.
