AngularJS enhances the HTML by including the concepts from various programming languages, both JavaScript and server-side languages and makes HTML the dynamic language too. AngularJS lets us to extend HTML vocabulary with new attributes for web applications or pages. The resulting environment is expressive, readable, and quick to develop.
