I am facing a situation where I have an if statement that needs to halt execution but only after certain processes have been completed. This if statement is enclosed within a forEach loop in an Angular context.
angular.forEach($scope.obj, function ( value, key) {
if( id == key) {
delete $scope.obj[id];
result.clicked = false;
//break here, don't run the else
} else {
$scope.obj[id] = result;
result.clicked = true;
}
})
It is impossible to achieve this using Angular's forEach loop as it does not support breaking on a condition match. Consider using a traditional FOR loop instead of angular.forEach as the for loop allows you to break out of the loop when needed.
After reviewing the Angular documentation thoroughly, it appears that there is no clear indication of how to stop a forEach loop. It seems that once it starts, it must run to completion. One alternative approach could be to consider using Array.prototype.every instead. On the other hand, forcibly stopping the forEach loop may be possible, but it could be considered a hacky and unreliable solution.
When working with Angular.forEach, you must keep in mind that it operates asynchronously, meaning you cannot simply break out of the loop. However, with a traditional loop, breaking out is possible as usual.
