hang is micro helper function that will guarantee that your callbacks are
called async. The returned function can be called in sync or completely async.
When it's called in
sync we will "hang" execution in a
setTimeout(0) to ensure that it's called in async.
The module is released in the public npm registry and can be installed by running:
npm install --save hang
Require the module and supply it the function that should be called in completely async:
'use strict'; var hang = ; var fn = ; fn //// Or call it "async"//;
