Introduction

JQuery is a feature-rich and lightweight JavaScript library built on the concept of “write less, do more.” Its basic APIs make tasks like HTML document manipulation, event management, and applying animation effects to a web page more manageable. It operates through all major browsers such as Chrome, Firefox, Safari, Internet Explorer, etc. 

When you learn JQuery, you can quickly and easily construct an Ajax-based programme. JQuery is used by big corporations like Google, Microsoft, and IBM in their apps. With JQuery, you will save a lot of time and effort. As open-source software, JQuery is run and managed by a collaborative community of developers.

What is JQuery? 

JQuery is a versatile and efficient JavaScript library developed in 2006 by John Resig. JQuery’s principle is “write less, do more,” which is very fitting given that the majority of its features revolve around simplifying each line of code. The following is a collection of JQuery’s most important features: 


  • Simplified JavaScript: It enables accelerated web creation by simplifying DOM manipulation and event handling. 
  • Handling of events: JQuery enables capturing a vast range of activities, such as a user clicking on a page, without clogging up the HTML code. 
  • Weighs little: JQuery is a tiny, lightweight library that is approximately 19KB in size. 
  • Animatronic: It includes a slew of built-in animation effects that you can use to enhance the interactivity of your web application.

Why use JQuery? 

At the moment, a large number of developers have jumped on the JQuery bandwagon, and why shouldn’t they? JQuery identifies cross-browser incompatibilities, interoperability problems, and standardisation issues. It establishes an abstraction layer that handles all workarounds. Let’s have a look at some of the reasons JQuery is so common at the enterprise level. 

  • Advocates for simplicity: Anyone new to the JavaScript environment would find it very intuitive and easy to learn JQuery. It has a straightforward syntax and adheres to free coding principles, enabling you to build beautiful websites. 
  • Displayed despite disabling JS: Numerous rendering issues can occur if Adobe Flash is not enabled on any browser. As a result, developers must invest much time coding for browsers that lack flash plugins. However, with JQuery, they are no longer required to do so. 
  • Produces animated applications: As with Flash, JQuery combines HTML, CSS, JS, and AJAX to create stunning results. As a result, you won’t need to employ a different Flash creator. 
  • Pages load rapidly: As a page loads slowly, it affects the success and rating of your website in search engines. The most effective approach to reducing load time is to use coding practices that involve the fewest possible lines of code and achieve the desired outcome. JQuery allows you to load tags only when they are needed, which improves performance. 
  • Search engine optimised: Numerous plugins are required to assist you in optimising the JQuery excerpts for search engines. You should embed any of the components using basic unordered lists, an excellent and safe technique for increasing your SEO score.
