10 Must-Have JavaScript Libraries You Shouldn’t Miss

A JavaScript library is a collection of pre-written JavaScript that allows for easier development of applications based on JavaScript, especially for AJAX and other web-based technologies. The primary purpose of JavaScript is to write functions that are either embedded in or included from HTML pages, and interact with a page’s Document Object Model (DOM).

In today’s roundup, we’re going to showcase some of the best JavaScript libraries to help you simplify web-related tasks and to give your site an edge among the competition. We hope you’ll find them useful for your web-related needs.
