In AngularJS, the $timeout service is used for delaying the execution of a function. It's similar to JavaScript's native setTimeout function but integrated into the AngularJS framework, allowing you to work with AngularJS's digest cycle

$timeout(function(){
    $scope.Label = "Show after two seconds";
}, 2000);

Example- 

<!DOCTYPE html>
<html ng-app="myApp">
<head>
    <title>$interval Service Example</title>
    <meta name='viewport' content='width=device-width, initial-scale=1'>
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.3/dist/css/bootstrap.min.css" rel="stylesheet"
        integrity="sha384-QWTKZyjpPEjISv5WaRU9OFeRpok6YctnYmDr5pNlyT2bRjXh0JMhjY6hW+ALEwIH" crossorigin="anonymous">
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.8.2/angular.min.js"></script>
</head>
<body>

<div ng-controller="myController">
    <div class="container my-4">
        <div class="text-center">
            <p class="fw-semibold">{{Label}}</p>
        </div>
    </div>
</div>

<script>
angular.module('myApp', [])
.controller('myController', function($scope, $timeout) {
   
    $scope.Label = "Hello Developer!";
   
    // update the Label text after 2 second      
    $timeout(function(){
        $scope.Label = "How are you?";
    }, 2000);
});

</script>
</body>
</html>

Output- 

   Hello Developer!

after two seconds

    How are you?
