HTML

 It replaces it with the contents of the variable.

<div id="main" ng-app>


<nav class="{{active}}" ng-click="$event.preventDefault()">



<a href="#" class="home" ng-click="active='home'">Home</a>
<a href="#" class="projects" ng-click="active='Hardware'">Hardware</a>
<a href="#" class="services" ng-click="active='Software'">Software</a>
<a href="#" class="contact" ng-click="active='contact'">Contact</a>
</nav>



<p ng-hide="active">Please click a menu item</p>
<p ng-show="active">You chose <b>{{active}}</b></p>
</div>

<div ng-app>
  <input type="text" ng-model="name">
   <div ng-repeat="i in [1]">
       <input type="text" ng-model="name"><br/>
        First scope:{{name}}
   </div>
   Second scope:{{name}}
</div>

function TodoCtrl($scope) {

}

jQuery:

• jQuery is Library
• JQuery sometimes is a very slow to manipulate the DOM
• Also an slow way to manipulate the DOM, affecting in this way the user experience.
• the jqlite and pure javascript to manipulate the DOM and follow the best practices to create  directives.
• jQuery is a JavaScript library that handles ways to manipulate your HTML. 
• It ensures that your code will be compatible as this library is maintained by a huge group of experts.
• JQuery is definitely something that front-end developers should know well before even touching Angular, 
•  jQuery is less prone to that.
•  I do MVC and jQuery is a part of the view, but the Model and Controller are made in server-side technologies

Angular JS

• AngularJS is a FRAMEWORK 
• to create a complex web app for which you need a massive amount of Javascript and keep it organized, flexible and manageable? Use AngularJS. In fact, AngularJS has jQuery built-in (jqLite).
• Angular is an JavaScript structural framework that has a lot of the effects similar to jquery, but is a more designed to create one-page web applications. 
• It is also open source and compatible. Angular often plays along with other technologies for quick efficient development or larger web applications.
• Angular will often seem like an extremely opinionated and hard to grasp beast. Angular is a framework, and like with every framework out there, you need to understand the language(s) it employs. I say learn to walk before you run, and don't become a snob who wants to do everything in Angular just because it sounds cool. 
• Angular is going through pretty significant changes and its versions tend to break things.
• AngularJS would be an overkill to make another MVC over the View layer whereas the Controller and Model are server-side
• Mobile apps and MVC but have no server-side technologies behind, so the MVC structure implemented in AngularJS.

Common Comments

If you are learning front-end development, concentrate in jQuery for now.
