// - Pending - response is not ready yet. Please wait.
// - Fulfilled - response is ready. Success. Take the data.
// - Rejected - an error occurred. Handle it.var promise = new Promise(function(resolve, reject) {
  // do some long running async thing…
  
  if (/* everything turned out fine */) {
    resolve("Stuff worked!");
  }
  else {
    reject(Error("It broke"));
  }
});
