What is JQUERY, and What is it used for?

WHAT IS JQUERY, AND WHAT IS IT USED FOR? 

In today's topic we will learn about what is Jquery? If you’re interested in started a high paying, flexible career as a web developer, then one of the first programming languages you need to learn is JavaScript. JavaScript is a coding language used to build dynamic web content like animated features, interactive forms, and scrolling video. But if you’re learning JavaScript (or “JS” as it’s abbreviated in tech), you also need to familiarize yourself with a JS-related tool called jQuery.

jQuery is a JavaScript library that allows web developers to add extra functionality to their websites. It is open source and provided for free under the MIT license. In recent years, jQuery has become the most popular JavaScript library used in web development.

To implement jQuery, a web developer simply needs to reference the jQuery JavaScript file within the HTML of a webpage. Some websites host their own local copy of jQuery, while others simply reference the library hosted by Google or the jQuery server. For example, a webpage may load the jQuery library using the following line within thesection of the HTML:

If you’re new to coding, this might sound like cheating. Shouldn’t you be writing your own code? The reality is—for certain routine coding tasks—there’s absolutely no point in reinventing the wheel. You probably wouldn’t manufacture your own wood when building a house, and coding is no different. jQuery allows web developers to plug routine JavaScript features into a web page so they can spend more time focusing on complicated features that are unique to their site.

WHY USE JQUERY?

In addition to understanding WHAT jQuery is, it’s helpful to understand WHY developers use it. We’ll delve deeper into some of these points below, but here’s a list to provide the TLDR:

• jQuery makes JavaScript programming is Fast and more efficient
• jQuery is open source (meaning anyone can contribute to or modify it) and has a large user community, meaning it is consistently supported and added-on to.
• jQuery has extensive documentation (including in-line code examples!)
• jQuery plays well with any other JavaScript libraries you might be using
• jQuery has a TON of plug-ins that let you extend jQuery’s functionality as needed
