Is JQuery Still Relevant Today for Web Developers?

Is JQuery still relevant today for Web Developers

The usage statistics posted on several websites depict the massive popularity of jQuery among modern web application developers. According to, “JQuery is used by 70.8% of all the websites, that is a JavaScript library market share of 96.2%.” Also, the JavaScript library is currently being used by large technology companies like Google, Microsoft, IBM and Netflix. Hence, jQuery is currently popular among large and reputed companies as well as small companies and start-ups.

Despite being more popular than other JavaScript libraries, jQuery is both concise and lightweight. But it enables web developers to use JavaScript more efficiently on the websites, and accomplish common programming tasks without writing longer lines of code. At the same time, the JavaScript library provides features to simplify complex programming tasks like DOM manipulation and AJAX calls. There are also a number of reasons why modern web developers prefer jQuery to other JavaScript libraries.

Why Modern Web Developers Prefer jQuery to Other JavaScript Libraries?

Lightweight: As mentioned earlier, jQuery is a lightweight and concise JavaScript library. Its original footprint is smaller than the high resolutions images used by a website. Also, developers can compress the library after developing and debugging the code to enhance the application’s performance and reduce bandwidth consumption. Hence, it becomes easier for programmers to use the JavaScript library across multiple web pages without affecting the load speed and performance of the website adversely.

Easy to Use: Despite being lightweight, jQuery enables programmers to accomplish both simple and complex programming tasks without writing longer lines of code. Its simple syntax further helps developers to add features or functionality to the website without writing complex code. Hence, many web developers find it easier to use jQuery in comparison to other JavaScript development tools.

Multiple Installation Options: The web developers have option to install jQuery in two distinct ways. They can download the library to their local system, and then include it in HTML code. Otherwise, they can integrate jQuery directly into the HTML code by using a content delivery network (CDN). The CDN enables users to make the web browser cache jQuery across various applications.

DOM Manipulation: Many web developers nowadays try to enhance the performance of the web application through document object model (DOM) manipulation. JQuery enables programmers to manipulate DOM without writing additional code. The developers can avail specific methods like .val(), .html() and .attr() to simplify DOM manipulation. These methods further help programmers to quickly accomplish tasks like modifying value of attributes of an element and extracting HTML code from a division.

AJAX Calls: The web developers can further use jQuery to build AJAX templates without putting extra time and effort. Hence, the developers can keep the user interface of the web application slick by creating and using a variety of custom AJAX templates. Also, they can perform common tasks without refreshing or reloading the web page fully. Hence, jQuery enables developers to make the website deliver dynamic and update content to each user without writing lengthy and complex code.

Event Handling:  While using jQuery, the developers can capture various events more elegantly. The JavaScript library further enables programmers to capture events elegantly without incorporating event handlers in the HTML code. The web programmers can simply use jQuery Event Model to establish event handlers directly on the DOM elements through the bind() method.

Reduced Cross-Browser Issues: JQuery supports various versions of major web browsers like Chrome, Firefox, Internet Explorer, and Safari. The developers have written jQuery specifically to run across multiple web browsers in an exact and identical way. Hence, the web developers are not required to handle cross-browser issues, and check how a specific web browser implements JavaScript. They can include jQuery in their source code of the application without worrying about the version or type of the web browser.

Extensible: As a lightweight JavaScript library, jQuery does not come with additional functionalities. But the users can easily extend the functionality of jQuery by using a wide variety of open source plug-ins. Each jQuery plug-in designed as a standard JavaScript file, and contains specific jQuery function which can be integrated seamlessly into the jQuery library methods. The members of jQuery community further upload new plug-ins on a regular basis to complement the emerging trends in web application development.

Increased Search Engine Ranking: Major search engines like Google ranks websites by using a variety of metrics. Also, the search engines need to access and read the source code of the web application without any hurdles. Hence, web developers have to explore ways to make the source code of a website fully readable and accessible for search engines. JQuery along with all its components are set up as text. The search engines will rank the website higher by accessing and reading its source code fully.

Keeps Evolving: Despite being an open source JavaScript library, jQuery keeps evolving continuously. The web application developers can use jQuery 3 to avail a number of new features like option to iterate over DOM elements, use new signatures, and modified behaviours. Also, the JavaScript library now supports several advanced technologies including basic XPath syntax and CSS selectors. The users can further avail the new plug-ins updated by members of thriving jQuery community to create web applications rapidly according to the latest industry trends and user preferences.

However, jQuery, like other JavaScript libraries, has its own shortcomings. For instance, it restricts options to customize a website fully by using raw JavaScript. Likewise, it requires programmers to execute jQuery commands through Query JavaScript file which contains all its events, effects, DOM and AJAX components. But the developers still prefer using jQuery to accomplish a variety of tasks without writing additional code. They also have option to integrate jQuery with other web application development tools to deliver custom web applications within a shorter amount of time.
