promises are nothing more than async functions
Raw
gistfile1.js
function onSuccess(val) { ... }
function onError(err) { ... }
try {
onSuccess(g(f(42))); // function composition
}
catch(e) {
onError(e)
}
Q.delay(42, 1000).then(f).then(g).then(onSuccess, onError);
// Promises let you compose async functions. Nothing more, nothing less.
