async-debounce
Debounce asynchronous functions.
Debouncing means that given function is only run after no calls to it have happened for x
milliseconds. With functions that do asynchronous work, i.e. not finish in the same tick, you also want no calls to happen while the function is currently running - limit the concurrency to one - and rerun with new arguments afterwards.
Example
var debounce = ; { console; ;} var debounced = ; console; ;;;
And in the output you can see that the function is run at max once at a time and if the debounce triggers while the function is still running, it will be queued.

API
fn = debounce(fn, interval)
Returns a decorated version of fn
that when called calls fn
only when no further calls have happended for interval
milliseconds and if it's not currently running. When it's done running and a call has happened while it was still running, it's called again with latest arguments.
