Question

(a) clearInvocation()

(b) cancelInvocation()

(c) clearInterval()

(d) clear()

This question was posed to me in an interview.

Answer 1

Right answer is (c) clearInterval()

The explanation is: Like setTimeout(), setInterval() returns a value that can be passed to clearInterval() to cancel any future invocations of the scheduled function. The ID value returned by setInterval() is used as the parameter for the clearInterval() method.
