setImmediate polyfill for the browser and node. This is an alternative to setTimeout(fn, 0), which behaves like setTimeout(fn, 4). setAsap will execute immediately. It has unmatched performance and is extremely lightweight.
npm install setasap --save
setAsap(function() {
// do something async
});
Currently, there is no way to cancel setAsap. The code base is much smaller without it.
