What Is AngularJS?

Angular is a web application framework developed by Google that was first released to the public in September 2016. It is ideal for building dynamic web applications and is modular by nature. Angular supports the MVC architecture and offers two-way data binding. It is also open-source and supports most popular browsers.

Angular applications are composed of component classes that define many views. Each component is associated with a root component, which connects to the DOM. Every component defines a class to store the application's data and an HTML template. Angular creates a component-specific template by applying an @Component() decorator to the JavaScript class that represents the component. The decorator applies Angular directives and binding markup to the HTML before rendering it.

Angular also supports two-way data binding, which allows the DOM to be changed by the program and then reflected in the HTML code. Data binding also allows dynamic behavior to be injected into Angular web pages. In most cases, this two-way data binding happens between the view and model components. Angular also converts the rich template syntax into efficient code, which helps developers write code faster.

Angular has evolved and changed a lot since its initial release. It now uses the Ivy renderer, which has several deprecations and compatibility issues. It has also improved its IDE and added workspaces, which let developers host multiple Angular projects. This makes it easier to migrate to new versions.
