Background task

An simple function wrapper around requestIdleCallback that queues tasks and runs them sequentially.

The main purpose is to be able to run maintainance functions that are not a good fit for a web worker context.

Usage

Wrap your function.

		const task = backgroundTask(() => {
			// do stuff
		});

Call task as you would any other function that has no return value. The return value of a background task is the id from requestIdleCallback that can be passed to cancelIdleCallback if you wish to cancel the task before it runs.

Calling a task multiple times will queue the passed parameters and execute the task sequentially the same number of times.
