AngularJS ng-bind attribute tells Angular to replace the text content of the specified HTML element with the value of a given expression. It also updates the text content when the value of that expression changes.
<div ng-app="myApp" ng-controller='MyCtrl'>
Enter Name: <input type="text" ng-model="name" ng-init="name='John'"><br>
Hello <span ng-bind="name"></span>!
</div>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.5.3/angular.min.js"></script>
<script>
var module = angular.module('myApp', []);
module.controller('MyCtrl', function($scope) {});
</script>
