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

Conceptual Illustrating Garbage Collection The 'obj' object is now eligible for garbage collection. The JavaScript engine will eventually reclaim the memory. You won't see a specific indication, but memory usage would decrease over time or in subsequent memory allocations.
