The Ext JS or Extended JavaScript is a JavaScript framework which can be used to develop web-based desktop applications with rich UI. However, the Sencha Touch framework is optimized to create web-based mobile applications such as smartphones and pads. This is the prime difference between these two.
It’s a comprehensive Java framework which can be used to build feature-rich web applications. The framework uses the GWT compiler. This allows developers to produce an application in Java and compile them into cross-platform HTML5 code which is highly optimized.
The GUIs supported by the Sencha Touch are:
- CSS3 and HTML5 for higher flexibility.
- I have enhanced touch events.
- Excellent support for animations.
- Easily scales to various resolutions for best compatibility with various Android and iPhones.

These are the most user preferred Sencha tools, Sencha Inspector, Sencha Architect, Sencha Cmd, Sencha Themer, Sencha GXT, Stencils and Sencha IDE and Code Editor Plugins.
Sencha Cmd is required to build Ext JS applications. It offers many useful lifecycle management features to best compliment your Sencha projects, such as ES6 transpilation, code minification, scaffolding, dynamic package loading, building generation for progressive web applications, and more.
Sencha IDE and Code Editor Plugins are used to integrate enterprise Sencha frameworks into users’ enterprise workflow. The Plugins are extremely useful and offer code inspection, code completion, template generation, refactoring, code generation, code navigation and more. It works with Sencha framework classes, custom user classes and overrides.
The Sencha Themer tool helps users to style Ext JS 6 applications with a better user interface. Custom themes can be created with it using graphical tools, without writing any code. App developers will get access to all Ext JS inspection tools and components to set fine-grained styles and generate dynamic stylesheet including theme packages.
This tool empowers app developers to build HTML5 applications merely using drag and drop features. This saves a lot of valuable project time for developers which they use for manual coding. The code available here is also optimized to achieve high-level performance.
It’s a debugging tool used to get direct access for classes, components and more for applications using the Sencha framework. The Sencha Inspector tool lets developers analyze their code for issues and eventually helps in improving the performance of applications.
The app developers use Sencha MVC to separate the control code, the application data, and view. This separation helps large scale web applications to be flexible and maintain easily.
