Do you see a distinction in how ng-repeat is written in these two examples?
<div ng-repeat="item in getItems()">
Versus this:
<div ng-repeat="item in items">
Imagine getItems is structured like this:
$scope.getItems = function() {
return Object.values(objA).concat(Object.values(objB));
}
In the second scenario, I would need to keep track of updating the array items whenever objA and objB undergo changes.
Like I mentioned earlier, the second one in the question will hold a slight advantage over the first one.
<div ng-repeat="item in items">
This code will run through items that are initially loaded and evaluate the expression on each $digest cycle.
<div ng-repeat="item in getItems()">
In this case, you are invoking a function that will be executed multiple times during the $digest cycle, and you are concatenating arrays inside the function, which can affect performance negatively.
