Angular is a framework for developing applications in the browser. It is based on a series of TypeScript libraries and incorporates a number of ECMAScript 6 features. Angular’s structure is based around a few key concepts. First, NgModules serve as a compilation framework for directives and components. Modules are well-designed collections of interconnected code. A single application typically contains several such modules.
Each Angular application consists of components. The root component connects the component hierarchy to the DOM. Each component defines a class and an HTML template. Each component is identified by a decorator, called an @Component(), which identifies the class as a component. A decorator can change a JavaScript class to implement component-specific metadata. Angular uses these properties to allow the application to respond to user input.
The Angular programming language was first released in 2010 as AngularJS. It has undergone numerous enhancements and major updates throughout its history. Google, which developed Angular, has continued to support the framework by providing Long-Term Support (LTS).
A two-way data binding system between the view and the model is a key Angular feature. The two-way data binding system means that any changes made in the Model layer will be reflected in the view. This saves developers significant time, as they no longer need to manually link the MVC layers. Furthermore, Angular uses a low-code framework that separates directives from app code. This is a key feature of Angular, and one of its most significant advantages.
