Notes

AngularJS is a structural framework for dynamic web apps. It lets you use HTML as your template language and lets you extend HTML's syntax to express your application's components clearly and succinctly. Angular's data binding and dependency injection eliminate much of the code you would otherwise have to write. And it all happens within the browser, making it an ideal partner with any server technology.
AngularJS is Developed with a belief that declarative code is better than imperative code when it comes to building the UI's and writing softwares companents code together.
AngularJS is designed to overcome the problems of registering callbacks,manipulating html DOM Programmitically which Jquery doesand Marshalling data from UI to service frequently.

Templates:
In Angular, templates are written with HTML that contains Angular-specific elements and attributes. Angular combines the template with information from the model and controller to render the dynamic view that a user sees in the browser.
Directive — An attribute or element that augments an existing DOM element or represents a reusable DOM component.
Markup — The double curly brace notation {{ }} to bind expressions to elements is built-in Angular markup.
Filter — Formats data for display.
Form controls — Validates user input.
