[JavaScript] Remove an item from array

Scenario
Assume I have an array of data in $scope.tab2.sentence.entities
I would like to remove an item from array based on the value which I provide, how to do it?

How-To
You can utilize splice to fulfill the requirement.
Here has the code snippet:

 $scope.removeTab2Entity = function(entity) {
      var index;
      for (var i = 0; i < $scope.tab2.sentence.entities.length; i++) {
          if ($scope.tab2.sentence.entities[i].value == entity.value) {
              index = i;
              break;
          }
      }
      $scope.tab2.sentence.entities.splice(index, 1);
  }
