Checking whether clearInterval has been called?

Question

Given this code:

bob = setInterval(function, 1000);
clearInterval(bob);

Is there now a way to know if that interval has been cleared?

C

Answer 1

The return value of setInterval is just a unique id you use to pass back to clearInterval. It's not a structured object with any additional information, nor does it get set to null when you call clearTimeout.
