Difference Between ExtJS and jQuery

There are several computer languages available today that may be used to create web pages. The most popular Javascript frameworks are ExtJS and jQuery, primarily utilized to create websites with interactive interfaces. Although the names ExtJS and jQuery seem to be interchangeable, there are significant distinctions between the two.

ExtJS vs jQuery

The main difference between jQuery and ExtJS is that ExtJS is licensed under the GPLv3 and a commercial license, while jQuery is licensed by the GPL and MIT licenses, which allows for unrestricted usage. ExtJS is free to use if your application is open source and licensed under the GNU General Public License version 3. If your software is not open source, you will have to pay a fee of several hundred dollars to get a commercial license.

ExtJS vs jQuery

Ext JS is a pure Javascript framework with an extensive component library. Some refer to a framework such as Ext JS as an RIA framework (Rich Internet Applications). This eliminates the need to create extra HTML to build the frontend application. With Ext JS, you can create sophisticated apps that provide a comparable user experience to working on a desktop PC.

jQuery is a JavaScript library that is free and open source. Using this technique, JavaScript and DOM interactions between a CSS/HTML page are more straightforward (Document Object Model). Ajax, DOM (Document Object Model), cross-browser development using JavaScript, and HTML document modification and transport are all made easier with this tool.

Comparison Table Between ExtJS and jQuery

Parameters Of ComparisonExtJSjQuery
DefinitionExt JS is a robust JavaScript application development framework. It aids in the development of JavaScript-based data-intensive HTML 5 applications.jQuery is a JavaScript library that is free and open source. DOM animations, cross-browser JavaScript programming, and HTML document manipulation and transit are all made easier with this plugin.
ComplexityExtJS is a more powerful tool than jquery, however, it cannot be used with HTML due to its simplicity.It’s a simple scripting language that focuses on HTML element interactions.
Page ReloadExtJS can reload a page after it has been loaded once.It is not possible to refresh a web page after it has been loaded.
Server OverloadingExtJS use may result in server overloading, since each time a JS call is made, the number of connections increases.There is no possibility of a server overload while dealing with jquery.
FunctionalityIt is a synthesis of many different technologies like JS, DOM, CSS, and HTML that adds a plethora of additional capabilities.Jquery is incapable of creating new technologies via the combination of existing technologies.

What is ExtJS?

Ext JS is a robust JavaScript application development framework. You can use JavaScript to build data-intensive HTML 5 apps. We can utilize JavaScript and the Ext JS framework to create business applications without writing CSS or HTML 5 code. It offers a comprehensive collection of UIs (User Interfaces) for building cross-browser online applications.

The desktop application development framework Ext JS is quite popular. Firefox, Chrome, Safari, and Opera 12+ are all compatible with it. Because of its built-in themes and UI components, Ext JS speeds up development. ExtJS combines several different technologies, such as JS, DOM, CSS, and HTML, and offers a wide range of additional features. It’s a phrase that refers to a collection of technologies rather than a single one.

While ExtJS is a more sophisticated tool than jquery, it does not work with HTML since it is a more straightforward tool. When a user uses it without refreshing the page, its content is updated exceptionally quickly. As the operation takes place in the background, the user won’t see that data is being exchanged on the page. ExtJS has many benefits. It’s simple to get started with ExtJS since it makes use of already-existing tools and technologies. Ultimately, it wants to make the internet more fun and engaging environment for everyone. There’s a high demand for pre-collapsed molds because of their widespread use.

What is jQuery?

jQuery is a JavaScript framework that allows developers to build cross-browser JavaScript applications and modify and transfer HTML pages effectively.
Sizzle is a cross-browser open source selector engine that makes it simple to pick DOM (Document Object Model) components and change their content. A wide variety of events may be captured appropriately using it.

JavaScript library jQuery is open source and free. JavaScript and DOM interactions across CSS/HTML pages are easier to understand when using this approach (Document Object Model). This tool simplifies Ajax, DOM (Document Object Model), JavaScript cross-browser development, and HTML document change and transfer. Ajax technology combined with Jquery makes for a feature-rich and responsive website. It comes pre-loaded with a slew of animation effects often seen on websites. It’s a pretty little library, just 19KB in size after being gzipped and minified. Thanks to its cross-browser compatibility, you may use it on Chrome, Safari, Opera, and IE 6.0+.

Using Jquery has several drawbacks. When using jquery, the application’s client must deal with many functions that were built using jquery. If it’s utilized too much, it slows down the users. Because of this, programmers must employ a different cache. It may do a variety of tasks, depending on the needs of the particular location. However, many capabilities remain unrealized. Jquery’s drawback is this.

Main Differences Between ExtJS and jQuery

  1. ExtJS is not free while jQuery is totally free.
  2. ExtJS is much easier to use than jQuery.
  3. ExtJS is not dependent on plug-ins whereas, jQuery is more dependent upon Plugins.
  4. ExtJS has offline storing capabilities, while jQuery does not.
  5. ExtJS can reload a page after it has been loaded once whereas, It is not possible to refresh a web page after it has been loaded in jQuery.


The most often used technologies for developing interactive web interfaces are ExtJS and jQuery. These two technologies contribute to the attractiveness and functionality of the online application. ExtJS and Jquery are both critical technologies, yet it’s difficult to tell them apart since ExtJS and jQuery are often used in conjunction.

However, the primary distinction between these two systems is that ExtJS communicates with the server through JavaScript rather than refreshing a web page. On the other hand, jQuery is written in JavaScript, which is more akin to a framework. Jquery makes extensive use of ExtJS in a number of its functionalities.
