AngularJS is an MV* framework that is ideal for use when buildingÂ client-sideÂ single-pageÂ apps. It isÂ not a library, but aÂ frameworkÂ for building dynamic web pages. It focuses onÂ extending HTMLÂ and providingÂ dynamic data binding, and it plays well with other frameworks (e.g., jQuery).
If you are building a single-page app, AngularJS will be perfect for you.Â Gmail,Â Google Docs,Â Twitter, andÂ Facebookall fit into the AngularJSÂ sweet spot. Game development and other apps that heavily manipulate the DOM or need pure speed are not good fits for AngularJS.
