neall / promiseTimeout.coffee
Created April 29, 2014 15:09
I wanted to make a promise-wrapped setTimeout that had a way to abort. I am not 100% happy with just giving the promise an abort() method.
promiseTimeout = (delay) ->
extraMethods = {}
promise = new Promise (resolve, reject) ->
handle = setTimeout(resolve, delay)
extraMethods.abort = (reason = new Error('timeout aborted')) ->
if handle
clearTimeout(handle)
reject(reason)
handle = false
promise.abort = extraMethods.abort

Take a method that depends on "this" and wrap it in a function call you can pass around. Also includes optional currying.
Object.defineProperty(Object.prototype, 'methToFunc', {
value: function(methodName) {
var method = this[methodName];
if (typeof method === 'function') {
var curryArgs = [].slice.call(arguments, 1);
var that = this;
return function() {
return method.apply(that, curryArgs.concat(arguments));
};
} else {
