What is AngularJS?

AngularJS is a client-side JavaScript MVC framework for developing a dynamic web application. AngularJS was originally started as a project at Google, but now, it is an open source framework.

AngularJS is completely based on HTML and JavaScript, so no other syntax or language learning is required.

AngularJS is also simply called “Angular”.

AngularJS converts static HTML into dynamic HTML. It extends the capability of HTML by adding built-in attributes and components and also provides the ability to create custom attributes using simple JavaScript.

Why to Learn AngularJS?

AngularJS is an open-source web application framework. It was originally developed in 2009 by Misko Hewry and Adam Abrons. It is now maintained by Google. Its latest version is 1.2.21.

  • AngularJS is an efficient framework that can create Rich Internet Applications (RIA).
  • AngularJS provides developers with the option to write client side applications using JavaScript in a Clean Model View Controller (MVC) manner.
  • Applications written in AngularJS are cross-browser compliant. AngularJS automatically handles JavaScript code appropriate for each browser.
  • AngularJS is open source, completely free, and used by thousands of developers around the world. It is licensed under the Apache license version 2.0.

Overall, AngularJS is a framework for building large-scale, high-performance, and easy-to-maintain web applications.

Why Use AngularJS?

Listed below are the various features and reasons for which AngularJS should be used in web application development.

  • Data binding: The platform provides automatic sync of data between the model and the visual content and, as a result, it saves a lot of time as well as effort.
  • Controller: These are JavaScript that are bound to a particular scope.
  • Services: AngularJS has many built-in services. Like $ https
  • Filter: It helps select a subset of items from an array and returns it to a new array.
  • Instructions: They are markers on DOM elements such as properties, CSS elements, etc. They can be used as custom tags of HTML.
  • Routing: Helps to build single page application. It is specified in the URL after the # sign and enables you to create separate URLs for different content in your application.
  • MVC: stands for Model, View and Controller. It is a design pattern and is used for segmentation into various parts of the app, namely, model, view, and controller.
  • Deep Linking: This feature of App Framework helps you to encode the status of the application in the URL to bookmark. Later, the application can also be restored from the URL in the same state.
  • Dependency Injection: AngularJS also has an in-built dependency injection subsystem that can be helpful for developers to make the development and testing process easy, harmonious and straightforward.
  •  Scope: These are objects that act as the glue between the controller and the view.
