And Then...

A super-minimal CommonJS-like promises library with literate syntax. Comes with intelligent parallel execution, exception handling,

Loosely based on the documentation of kriskowal's q library.

The twist

What if you want to do them in parallel, but wait for all of them to be done?

longOperation(1).
and(longOperation(2)).
and(longOperation(3)).
then(function(firstResult, secondResult, thirdResult) {
  console.log("Awesome!");
})

Mix 'em up

If you use Gantt charts to model control flow.

longOperation(1).and(
  longOperation(2).and(longOperation(3)).
  then(function(secondResult, thirdResult) {
    return someOperation(secondResult, thirdResult);
  })
).then(function(firstResult, resultOfOperation) {
  console.log("All done!");
});
