Why jQuery is more popular than other JavaScript Libraries?

Each web application developer nowadays has option to choose from several open source JavaScript frameworks and libraries according to his specific needs. But the usage statistics posted on various websites indicate that jQuery is currently more popular than other JavaScript libraries. Also, JQuery is currently being used by large companies like Google, IBM and Microsoft. Unlike other JavaScript, jQuery is both lightweight and simple.

It is also designed as a JavaScript toolkit to enable developers to accomplish common tasks without writing longer lines of code. The web developers can take advantage of core features of jQuery to accomplish common tasks like animation, DOM manipulation, event handling and AJAX. There are a number of reasons why many web developers prefer jQuery to other JavaScript frameworks.

Features that Make jQuery More Popular than Other JavaScript Libraries

Lightweight: As noted earlier, jQuery is a lightweight JavaScript library with a footprint of 32 KB. The footprint of the library is smaller than the high resolution images used by the website. Hence, it becomes easier for the web browser to download jQuery once, and cache it for multiple web pages. The developers can further use a content delivery network (CDN) to make the browser use the cached jQuery across multiple websites.

Easy to Use: Despite being lightweight, jQuery enables developers to perform many functions without putting extra time and effort. The simple syntax enables programmers to add functionality to the web application with less code. At the same time, the developers can reduce development time significantly by availing a wide variety of plug-ins.

Facilitates DOM Manipulation: JQuery simplifies DOM manipulation by providing a number of methods including .val(), .html() and .attr(). These methods enable programmers to manipulate the DOM of web page without writing additional code. The developers can take advantage of these methods to perform tasks like extracting HTML code from a division or modifying values of an attribute of the elements.

Supports AJAX: As jQuery supports AJAX technologies, it becomes easier for developers to build a variety of responsive and feature-rich web applications within a shorter amount of time. They can further take advantage of the JavaScript library to build robust AJAX templates easily. The feature further makes it easier for programmers to deliver updated content and data to end users without reloading the entire web page.

Effectuates Event Handling: JQuery allows programmers to capture various events in a more elegant way. Further, they have option to capture the events without including event handlers in the HTML code. They can take advantage of the jQuery Event Model to establish event handlers directly on DOM elements using the bind() method.

Handles Cross-Browser Issues: Each web browser implements JavaScript in a different way. So while building JavaScript applications, developers have to put extra time and effort to address various cross-browser issues. But jQuery is designed with features to make JavaScript code run seamlessly on each browser. Hence, the users are not required to worry about the way JavaScript is implemented by individual browsers or address issues related to cross-browser compatibility.

Boosts Page Load Time: When a developer does not use jQuery, he has to write additional code to add functionality to the web application. But jQuery enables programmers to accomplish common tasks without writing additional code. The library helps programmers to keep the front-end files smaller, and make the web pages load faster. The optimized page load time will boost the application’s user experience and search engine ranking.

Highly Extensible: As a lightweight framework, jQuery is designed only with essential features. Hence, the web page is not required to download any features that are unnecessary and irrelevant. But its plug-in architecture makes jQuery highly extensible. The library enables users to choose from a wide range of official and third-party plug-ins. The developers can further take advantage of the plug-ins shared by members of the community extend the jQuery library without putting extra effort.

Increases Search Engine Visibility: While ranking websites, the search engine must access and read its resources without any hassle. Unlike other web frameworks, jQuery and all its components are set up as text. Hence, the search engine can easily read and scan the source code of the application efficiently. The feature makes the website rank higher on major search engine results pages.

Despite being open source, jQuery has been evolving consistently. The developers recently make the Release Candidate for jQuery 3.0 available for review and testing. The new features and enhancements included in the updated version of jQuery will enable developers to build modern web applications rapidly. Also, the new features and enhancements keep the massive popularity of jQuery intact in the longer run.
