Question

What is the reason behind 'continue' not functioning properly in an Angular forEach loop?

I have a particular issue with my Angular app. I am using an angular.forEach function and trying to skip some values by using the continue keyword, but for some reason it's not working as expected.

<div ng-app="app">
  <div ng-controller="test">
    test
    {{printPairs()}}
  </div>
</div>

angular.module("app", [])
       .controller("test", function($scope){
          var array = [1,2,3,4,5,6];

          $scope.printPairs = function(){
            angular.forEach(array, function (elem) {
              if(elem % 2 === 1){
                 continue;
              }
              //More logic below...
            })
          };
       });

Can anyone explain why this behavior is occurring?

Answer №1

This issue arises because you are not within a javascript foreach loop.

However, since we are in a function, you can observe that angular.forEach's second parameter is a callback that is executed in each iteration.

To resolve this problem, you can simply use a "return" statement to skip the current position that meets your if condition, like so:

angular.forEach(array, function (value, key) {
     if(1 === value % 2){
        return;
     }
     //Additional logic below...
 })
