Sworn is a promise library based on Promises/A+ specification and other features.

The Promises/A+ specification includes a object Promise with a function then with the signature promise.then(onFulfilled, onRejected). Read more about it on MDN and Promises/A+.

• onFullfilled: (value) -> void
• onRejected: (reason) -> void

Other than the specification there are there are catch and fail (promise.[catch|fail](onRejected)) which are just a shorthand for promise.then(onFulfilled, onRejected).

Promise.all(array) that takes a array of promises (can be mixed with regular values). And resolves all of them in parallel and resolves the array to the next then call.

Promise.race(array) that takes a array of promises (can be mixed with regular values). And resolves the first one to be done.

This library was a product of a school project about JavaScript optimization. As I am not great at writing it is kind of short but. (It is in swedish)
