Sencha Ext JS is the most comprehensive JavaScript framework for building data-intensive, cross-platform web and mobile applications for any modern device. Ext JS includes 140+ UI components, such as HTML5 calendar, grids, pivot grid, D3 adapter, trees, lists, forms, menus, toolbars, panels, windows, and much more which helps make it one of the best Javascript libraries. The robust data package included in Ext JS decouples the UI components from the data layer. Hundreds of user extensions are also available from the Sencha community.

You can accelerate web application development with an enterprise-ready framework, components and tools built to work together seamlessly. You can improve the web app design process with pre-integrated tools like Sencha Architect, Sencha Stencils and Sencha Themer. Sencha Test is the most comprehensive unit and end-to-end testing solution for Ext JS.

Additionally, Ext JS includes a flexible layout manager to help organize the display of data and content across multiple browsers, devices, and screen sizes. It helps you to control the display of components, even for the most complex user interfaces. Ext JS also provides a responsive config system that allows application components to adapt to specific device orientation (landscape or portrait) or available browser window size.

Ext JS also includes features that align with the ADA Standards for Accessible Design. The Ext JS ARIA package makes it possible to add accessibility support to your applications by providing tools that you need to achieve Section 508 Compliance. Using the ARIA package, you can create apps that can be used by people who need assistive technologies such as screen readers to navigate the web.

In this article we will explore the ecosystem of all of the Ext JS libraries and tools that make it one of the best Javascript libraries.
