Can you explain the functionality of $timeout in AngularJS and how it sets itself apart from traditional setTimeout()?
Executing a function with a delay using $timeout:
$timeout(yourFunction, yourDelayInMS)
For example, displaying an alert after one second:
$timeout(function(){alert('hello'},1000);
The main distinction between $timeout and setTimeout is that $timeout is integrated into the angularjs digest cycle. When working with scope modifications in your code, it is recommended to use $timeout over setTimeout.
Let's say you're using setTimeout in your link function and you notice that the $scope variables are not updating as expected. In this case, you must implement a solution like the following:
window.setTimeout(function() {
scope.$apply(function() {
scope.myVar = "I have been updated"
})
},1000);
The $timeout function essentially simplifies this process for you.
