ExtJS

ExtJS is a comprehensive JavaScript framework for building data-intensive, cross-platform web applications with rich user interfaces. It provides a large collection of pre-built UI components including grids, trees, forms, charts, and layout managers. ExtJS follows an object-oriented architecture with a class system, data binding, and MVC/MVVM patterns. The framework includes powerful data management tools for handling large datasets, including stores, proxies, and models. It is designed for enterprise applications requiring complex interfaces and extensive data manipulation. ExtJS is widely used in corporate environments for internal applications, dashboards, and administrative interfaces where functionality and data handling capabilities outweigh framework size considerations.
