Promise syntactic sugar

No need to write .then in your promise chains. The promise is the .then function itself!

What it does?

It allows you to convert this

Promise.resolve(10)
.then(function(n){
    return n / 2
})
.then(function(n){
    return n * 3
})
.then(console.log.bind(console)) // -> 15

into this

sweeten(10)
(function(n){
    return n / 2
})
(function(n){
    return n * 3
})
(console.log.bind(console)) // -> 15

That's it!

You can play with it on jsFiddle

Examples

Sweeten promises are just promises and functions (thens) at the same time:

var result = sweeten(fetch('/my/api'))
             (function(res) { return res.json(); })
;

// Now you have a simple function that contains your result
result(console.log.bind(console));

// and it is still a promise!
result.catch(console.error.bind(console));

// and can be used as such
Promise.all([result, fetch('my/api/something/else')])
.then(/*...*/);

// or equivalent of the above
sweeten.all([result, fetch('my/api/something/else')])
(/*...*/);

Sweeten promise constructor:

var myStuff = new sweeten(function (resolve, rejext){
    setTimeout(resolve, 100, Math.random());
});

myStuff(function(myNumber){/*...*/}, function(error){/*...*/});
