AngularJS Features

AngularJS is not a single piece in the overall puzzle of building the client-side of a web application. It handles all of the DOM and AJAX glue code you once wrote by hand and puts it in a well-defined structure. This makes AngularJS opinionated about how a CRUD (Create, Read, Update, Delete) application should be built. But while it is opinionated, it also tries to make sure that its opinion is just a starting point you can easily change. AngularJS comes with the following out-of-the-box:

• Everything you need to build a CRUD app in a cohesive set: Data-binding, basic templating directives, form validation, routing, deep-linking, reusable components and dependency injection.
• Testability story: Unit-testing, end-to-end testing, mocks and test harnesses.
• Seed application with directory layout and test scripts as a starting point.

Angular has the following key features which makes it one of the powerful frameworks in the market.

• MVC – The framework is built on the famous concept of MVC (Model-View-Controller). This is a design pattern used in all modern day web applications. This pattern is based on splitting the business logic layer, the data layer, and presentation layer into separate sections. The division into different sections is done so that each one could be managed more easily.
• Data Model Binding – You don’t need to write special code to bind data to the HTML controls. This can be done by Angular by just adding a few snippets of code.
• Writing less code – When carrying out DOM manipulation a lot of JavaScript was required to be written to design any application. But with Angular, you will be amazed with the lesser amount of code you need to write for DOM manipulation.
• Unit Testing ready – The designers at Google not only developed Angular but also developed a testing framework called “Karma” which helps in designing unit tests for AngularJS applications.
• Angular 2 is faster and easier than Angular 1.
• It supports the latest version of browsers and also supports old browsers including IE9+ and Android 4.1+.
• It is a cross-platform framework.
• Angular 2 is mainly focused on mobile apps.
• Code structure is more simplified than the previous version of Angular.
