Angular is a technology used to create dynamic web applications. It is a component-based framework that provides the building blocks of the application. Each component defines an HTML template that defines the data contained in the application. It is written in TypeScript, which improves the maintainability of the code. The framework is open-source and backed by Google.

Angular has a two-way data binding system, which allows developers to easily manipulate data in both directions. This makes it easier to reuse data and cut down development time. The value of standard JavaScript variables can be set manually or retrieved from static JSON resources.

Angular’s two-way data binding is supported by a base directive called ng-bind. This directive establishes two-way data binding and resolves JSON before rendering templates. It is also used to tune model updates.

When Angular’s model changes, updates to DOM elements also reflect back to the model. This allows program logic to respond to user input. It also allows for the creation of a service class that shares logic with views.

Angular also provides a command-line interface (CLI). This allows developers to easily set up and test their applications. The interface is easy to use, and it includes test tooling out of the box. The CLI has been improved with workspaces and workspaces allow developers to host multiple Angular projects (more).

The framework has also undergone changes in type checking, syntax, and CSS style binding. It has also been updated with Google’s Material Design SDK.
