Promise

• Native implementation of promises. Yay!
• Promises/A+ spec compliant

var promise = new Promise(function(resolve, reject) {
  // Do something asynchronous and call resolve with the
  // result or reject with the error
});

promise.then(function(result) {
  // Use the result of the async call
}, function(error) {
  // Process the error
});

var allPromise = Promise.all([getLocation, getTemperature]);
allPromise.then(function([location, temperature]) {
  console.log('The location is ', location,
        'and the temperature is', temperature);
}, function(error) {
  // Process the error
});

var racePromise = Promise.race([getGoogleAds, getYahooAds, getBindAds]);
racePromise.then(function(ads) {
  page.addAds(ads);
});
