GarbageCollection (GC01)
1: function createObject() {
2: const obj = { name: 'Alice', data: new Array(1000000).fill(0) }; // Large array to consume memory
3: return obj; // Reference is returned
4: }
5:
6: let myObject = createObject();
7: myObject = null; // Remove the reference. After this the object is eligible for garbage collection
