- period(*required*): timer period(*units: milliseconds*).
### setInterval(initialDelay)
### setInterval([initialDelay], [invokeImmediate])
Start timer after a certain delay if specified.
Start timer after a certain delay(defaults to *0*) and can decide if invoke immediately(defaults to *false*).
Params:
- initialDelay(*optional*): Delay period(*units: milliseconds*) before timer gets triggered. *default: undefined*
- initialDelay(*optional*): Delay period(*units: milliseconds*) before timer gets triggered. *default: 0*
- invokeImmediate(*optional*): specify if the timer function invoke immediately.*default: false*
