Answer 1

When you talk about memory leaks in JS, it may be due to an unintentional global variables, persistant closures or detached DOM nodes which are still referenced.

There are few tools in DevTools which you can use to detect the above cases.

1. You can use a Heap Snapshot and see the allocations to which you have direct references from the code.

2. You can use the Allocation Timeline to link the heap snapshot information to a timeline and let you see where the memory is allocated.
