* - `resolve` Single shot function that resolves enclosed `promise` with a
* given `value`.
* - `reject` Single shot function that rejects enclosed `promise` with a given
* `reason`.
*
* An optional `prototype` argument is used as a prototype of the returned
* `promise` allowing one to implement additional API. If prototype is not
* passed then it falls back to `Object.prototype`.

*
* function fetchURI(uri, type) {

* request.open("GET", uri, true);
* request.responseType = type;
* request.onload = function onload() {
