What is Angular js?
AngularJS is a JavaScript-based front-end web application framework that was first released in 2010 by Google. The framework is used to develop web applications that are composed of HTML5, JavaScript, and CSS. It is designed to make it easier to build dynamic, single-page web applications and provides a number of features such as two-way data binding, dependency injection, and a powerful directive system. AngularJS uses a component-based architecture, and its latest version, Angular 11, was released in November 2020. Developers widely use it to build complex and high-performance web applications.
History of AngularJs
AngularJS was first released in 2010 by Google as an open-source web application framework. It was developed by Misko Hevery and Adam Abrons . The initial release of AngularJS was focused on providing a framework for building dynamic, interactive web applications. The framework used a declarative approach to building user interfaces, making it more structured and easier to understand than traditional JavaScript-based web development. It also introduced two-way data binding, which allowed changes made to the model to be automatically reflected in the view and vice versa. This simplified the process of updating the user interface.
The first version of AngularJS was met with positive feedback from the developer community, and Google continued to develop and maintain the framework. In 2013 , Google released AngularJS 1.2 , which introduced new features such as animations, new directives, and support for mobile devices. AngularJS 1.3 was released in 2014 , which included features such as a simplified directive definition and improved performance.
In 2016 , Google released Angular 2, a complete rewrite of AngularJS. Angular 2 introduced a number of new features and improvements, such as a simplified component-based architecture, improved performance, and support for newer web technologies. Angular 2 was not backward compatible with AngularJS, meaning developers had to learn the new framework to continue using it.
AngularJS is still widely used today, but Angular 2 and later versions have become more popular among developers.
Features of AngularJS
Directives: AngularJS uses directives to extend the capabilities of HTML by defining new elements or attributes. Directives are used to create reusable components and to add behavior to the DOM.
Data binding: AngularJS uses two-way data binding, which allows changes made to the model to be automatically reflected in the view and vice versa. This simplifies the process of updating the user interface.
Services: AngularJS provides a set of built-in services, such as $http and $resource, that can be used to make HTTP requests to the server and to interact with the web application's data.
Dependency injection: AngularJS uses dependency injection to manage the dependencies between different components of the application. This makes it easy to test and maintain the application.<l/i>
Routing: AngularJS provides a powerful routing feature that allows developers to create single-page applications with multiple views. This enables developers to build complex web applications with a clear structure.
Forms and validation: AngularJS provides a set of directives and services that can be used to create forms and to validate user input.
Unit testing: AngularJS provides a set of tools and best practices for unit testing the application, which helps in ensuring the quality of the code.
Performance: AngularJS provides various techniques and features to improve the performance of web apps, such as change detection, lazy loading and caching.
