jQuery is a collection of pre-written JavaScript code, known as a JavaScript library that one can add to one’s code. JavaScript is a standalone programming language, jQuery is a collection of JavaScript code. jQuery was first released in January 2006 by John Resig at BarCamp New York City.

It is designed to simplify the client-side scripting of HTML. It makes things like HTML traversal and manipulation, animation, event handling very simple with the help of an easily usable API (Application Programming Interface) that works on all popular browsers. jQuerymakes the usage of JavaScript easy on the website to make it more attractive, more interactive and animation-rich.

    If Adobe Flash is not installed in the browser, some parts of the page may not render or may not render properly. So, developers have to spend extra time coding for the browsers that don’t have Flash. With jQuery modifying the HTML DOM becomes easy, so content will be rendered even if JavaScript is disabled in the browser.

  • jQuery files are very small and load easily, so they can be optimized for site speed and helps in developing mobile-friendly websites, both of which are important factors towards SEO on search-engines. There are plugins available to display images, audio, and video files easily on web pages instead of embedding them directly.
