//Stupid "Bitmain" question about resolving promises.
//Run 3+ promises and check hoe many resolved and how many failed

//Stats variable
const stats     =   {success: 0, failed: 0};

//Some promise
const p = new Promise((resolve, reject) => {
    if(true) resolve();
    reject()

//Loop on set stats
const pArr = [p,p,p];
const run   =   () => {

        for(let promise of pArr) {
            promise
                .then(() => {
                    stats.success++;
                    //Resolve the run after all promises resolves
                    if(stats.success + stats.failed === pArr.length) resolve(stats);
                })

                    //Resolve the run after all promises resolves
                    if(stats.success + stats.failed === pArr.length) resolve(stats);

run().then(console.log);

//It's a stupid now because the question but because their answer includes Promise.all and
//wrapping each promise in another "fake" promise that always resolve it.
