Timers

All of the timer functions are globals. You do not need to require()
this module in order to use them.

setTimeout(callback, delay[, arg][, …])

Ruff available: v1.6.0
Ruff Lite available: v0.6.0

To schedule execution of a one-time callback after delay milliseconds. Returns a
timeoutObject for possible use with clearTimeout(). Optionally you can
also pass arguments to the callback.

It is important to note that your callback will probably not be called in exactly
delay milliseconds - Ruff makes no guarantees about the exact timing of when
the callback will fire, nor of the ordering things will fire in. The callback will
be called as close as possible to the time specified.

clearTimeout(timeoutObject)

Ruff available: v1.6.0
Ruff Lite available: v0.6.0

Prevents a timeout from triggering.

setInterval(callback, delay[, arg][, …])

Ruff available: v1.6.0
Ruff Lite available: v0.6.0

To schedule the repeated execution of callback every delay milliseconds.
Returns a intervalObject for possible use with clearInterval(). Optionally
you can also pass arguments to the callback.

clearInterval(intervalObject)

Ruff available: v1.6.0
Ruff Lite available: v0.6.0

Stops an interval from triggering.

setImmediate(callback[, arg][, …])

Ruff available: v1.6.0
Ruff Lite available: v0.6.0

To schedule the “immediate” execution of callback after I/O events
callbacks and before setTimeout and setInterval . Returns an
immediateObject for possible use with clearImmediate(). Optionally you
can also pass arguments to the callback.

Callbacks for immediates are queued in the order in which they were created.
The entire callback queue is processed every event loop iteration. If you queue
an immediate from inside an executing callback, that immediate won’t fire
until the next event loop iteration.

clearImmediate(immediateObject)

Ruff available: v1.6.0
Ruff Lite available: v0.6.0

Stops an immediate from triggering.
