What is AngularJS

• AngularJS is an open source JavaScript MVC framework for web applications.

• AngularJS extends Html behavior by creating custom tags or adding attributes in tags.

• AngularJS can be used to create Single Page Applications (SPA).

  Some of the reasons  would prefer AngularJS:

• You can create a template and reuse it in application multiple times.

• You can bind data to any element in two ways, where two-way actually means changing data will automatically change element and changing element will change the data.

• You can directly call the code-behind code in your html.

• You can validate forms and input fields before submitting it without writing a single line of code.

• Allows you to control complete DOM structure show/hide, changing everything with AngularJS properties.

• AngularJS allows you to write basic flow end-to-end testing, unit-testing, UI mocks.

AngularJS provides all the features you need to build a CRUD application like data-binding, data validation, url routing, reusable HTML components and most importantly dependency injection.
