Readme
Fate is a closure based implementation of Promises/A+
Promises and Futures
A promise
is an object with a then(onFulfilled, onRejected)
closure, making a promise a thenable
object.
A future
is a thenable
with bound fulfill(value)
and reject(reason)
closures. In fate, a future is also a valid node style function(err,arg)
callback.
fate.deferred()
returns an unresolved (pending) future
.
fate.fulfilled(value)
returns a fulfilled promise
.
fate.rejected(reason)
returns a rejected promise
.
