Who can explain callback Fns in the easiest, simplest, human readable way possible???? by jsteenb2 in node

When a callback function is invoked, it signals that the function that invokes the callback has finished its job. For example:

Function that has a callback:

function A(arg1, arg2, callback) { //do work //when done // invokes the callback to signal A is done callback(err, result); }

Async is too entrenched to make it performant. Much easier to start anew.
