AngularJS is a powerful JavaScript framework designed for building dynamic web applications. It provides developers with a structured and efficient way to create interactive and responsive user interfaces. AngularJS uses a declarative approach, where developers can define the behavior of their application using HTML templates and extending them with special attributes and expressions.
One of the key features of AngularJS is its two-way data binding capability. This means that changes made to the user interface are automatically reflected in the underlying data, and vice versa. This simplifies the process of keeping the UI and data in sync, reducing the amount of code required.
