The angular.bind() Function in AngularJS is used to bind the current context to a function, but actually, execute it at a later time. It can also be used in Partial Applications. Partial Application is when you want to make a function but some of the arguments have been passed already.
Syntax:
angular.bind(self, function, args);
Parameter Values:
- self: This refers to the context in which the function should be evaluated.
- function: It refers to the function to be bound.
- args: It is used to prebound to the function at the time of the function call. It is an optional argument.
Example 1: This example describes the implementation of the angular.bind() Function in AngularJS.

</script>
</head>
<body ng-app="app" style="text-align:Center">
<h1 style="color:green">GeeksforGeeks</h1>
<h3>angular.bind()</h3>
<p>Input number to sum with 5:
<div ng-controller="geek">
<input type="number" ng-model="num" ng-change="Func()" />
<br>Sum = {{Add}}
</div>
<script>
var app = angular.module("app", []);
app.controller('geek', ['$scope', function ($scope) {
$scope.num = 0;
$scope.Func = function () {
var add = angular.bind(this, function (a, b) {
return a + b;
});
$scope.Add = add(5, $scope.num);
}
}]);
