Angular.js, add string to name of variable?

Question

This might be a dumb question, but I can't figure this out. I have an array of objects with string values:

$scope.groups = [{name: "first"}, {name: "second"}];

And I have a bunch of items like this:

$scope.items = {first: [/*stuff*/], second: [/*stuff*/};

"first" and "second" are not explicitly defined, they are retrieved from server. Is there any way to use $scope.groups[0].name as a part of $scope.items.<here>? Or perhaps there's a better solution?

You can use JavaScript associative array syntax:

$scope.items[$scope.groups[0].name]

You can utilize this format to both get and set the value in $scope.items. You will, of course, need to at least initialize via $scope.items = {}; before attempting this.

Yes, you can define it as follows:

$scope.items[$scope.groups[0].name] = [/*stuff*/];
