}, 2000);
});
myPromise.then((ret) => console.log(ret));
myPromise.catch((ret) => console.log("ERROR: "+ret));
// ----- Example 2 -----
// Promise will be executed just when the method run is called
const babyPromise = require("babyPromise");
let myPromise = new babyPromise(async (p) => {
setTimeout(function() {
myPromise.resolve('Promise resolved');
//myPromise.reject('Promise error: Stack overflow');
}, 2000);
}, false); // <=== PAY ATTENTION HERE (autoRun parameter) !!!!
