when().then()

Pass when a function, once it returns true, the then function will be resolved.

when can be chained and will run synchronously.

when(condition).then(function() {
    // do something
})
.when(somethingElse).then(function() {
    // you can chain when synchronously
});

doUntil().then()

Pass doUntil a function that takes a parameter next, an async function can then be executed, calling next in it's own callback. If next is passed true, it will run again. Passing false will resolve the then function.

doUntil(function (next) {
    var item = input.shift();
    someAsyncFunction(function() {
        next(true); // passing false will resolve then()
    });
}).then(function() {
    // do something after
});
