javascript - Is there memory leak issue if not calling clearTimout after calling setTimeout

Question

After calling setTimeout, is there memory leak issue without calling clearTimeout?

Thanks.

No. clearTimeout only needs to be called if you want to stop a pending setTimeout from happening. After the setTimeout happens, the timer id is no longer valid but fortunately calling clearTimeout with an invalid timer id is harmless.

If you see memory leaks happening the problem is somewhere else.
