Angular is a popular open-source web application framework developed by Google. It was first released in 2010 as AngularJS and later rewritten in TypeScript to become Angular 2+ in 2016. Angular is widely used for building dynamic, single-page web applications (SPAs) and large-scale enterprise applications.
Angular follows the model-view-controller (MVC) architecture, where the application logic, presentation, and data manipulation are separated into distinct components. It emphasizes modularity, reusability, and testability, making it easier to develop and maintain complex applications.
One of Angular’s key features is its use of two-way data binding, which synchronizes the data between the model and the view automatically. This allows changes in the model to reflect in the view and vice versa, reducing the need for manual DOM manipulation.
Angular also provides a rich set of features and tools, including dependency injection, routing, forms handling, and HTTP client for interacting with backend services. It includes a comprehensive command-line interface (CLI) for generating components, services, modules, and other application artifacts, streamlining the development process.
Additionally, Angular offers built-in support for internationalization (i18n), accessibility (a11y), and progressive web app (PWA) features, enabling developers to create inclusive, high-performing web applications.
For example, here’s a simple Angular component that displays “Hello, World!”:import { Component } from '@angular/core'; @Component({ selector: 'app-hello-world', template: '<h1>Hello, World!</h1>', }) export class HelloWorldComponent {}
In this example, the HelloWorldComponent class is an Angular component with a template containing an HTML heading element (<h1>) with the text “Hello, World!”.
Angular’s comprehensive features, strong community support, and robust ecosystem of libraries and tools make it a powerful framework for building modern web applications.
