Angular JS is certainly considered as one of the most powerful JavaScript Frameworks. Chiefly this is dealt with the Single Page application commonly known as SPA projects. It appends HTML document object model with extra features and makes it more flexible as far as user actions are concerned. Angular JS is free and used by lots and lots of developers across the world.

A complete client-side solution

Angular 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 Angular 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. Angular 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.
