I have implemented a script to eliminate JSON objects from an array that exist in both the array itself and another JSON object:
var stageChildren = stage.sprites;
for (var i = 0; i < stageChildren.length; i++) {
for (var x in mainMenu) {
if (mainMenu[x] === stageChildren[i]) {
console.log(x);
}
}
}
To clarify, let's consider two objects named: object1 & object2.
In object1, there may be a common JSON object present in object2 as well. In such cases, the object is removed from object1.
Although this script functions correctly, I suspect it could significantly impact performance. Why? Because there are approximately 50 distinct objects within stageChildren, and 10 inside mainMenu. The script iterates through each object in stageChildren, checks if that object also exists within mainMenu (through another for loop), and proceeds to the next 49 objects.
Is there a more efficient method to achieve this?
