#myPromise

A lightweight shim/polyfill of ES6 promise, really easy to use:

    <script src="MyPromise.js"></script>
    <script>
        // simple
        new MyPromise(function(resolve, reject) {
            reject('x');
        })
        .then(onFulfilled, onRejected)
        //!!! ["catch"](onRejected) workaround for [IE8-]
        .catch(onRejected)
        .then(onFulfilled, onRejected);

        // complex
        new MyPromise(function(resolve, reject) {
            resolve(new MyPromise(function(resolve, reject) {
                // resolve(1);
                reject(new Error('reject in nested Promise'));
            }).then(function(future) {
                return future + 1;
            }, function(error) {
                return new Error('reject again in nested Promise');
            }));
        }).then(onFulfilled, onRejected);
    </script>

Everything is familiar with the original, only one prefix("My") is needed!
