    value or failure reason.
*/

      reject(err);
    });

Promise is a constructor function, so you need to use the new keyword to 
create one. It takes a function, as its argument, with two parameters - 
resolve and reject. These are methods used to determine the outcome of the
promise. 
The syntax looks like this:
*/

const myPromise = new Promise((resolve, reject) => {

});
