# Background task

An simple function wrapper around
[requestIdleCallback](https://developer.mozilla.org/en-US/docs/Web/API/Window/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.
