API

var debounced = debounce(fn, [ctx])

Returns a debounced version of fn with optional calling context ctx.

fn must be a function which returns a promise.

If debounced is called and no other call is currently pending, fn will be called and its promise returned. Otherwise - if another call is pending - the original promise will be returned.
