My question is about why there are two expected outputs from sololearn challenges in this chunk of ajax code but when I test in the debugger this gives me only [foo, car] as output?
const a = new Promise((res, rej) => { //n1
setTimeout(() => res('foo'), 300);
});
const b = new Promise((res, rej) => {
setInterval(() => rej('bar'), 100);
res('car');
});
Promise.all([a, b]).then((race) => {
console.log(race);
}).catch((crash) => {
console.log(crash);
});
Right answers:
[foo, car]
['bar', 'car']
- why this?
I have not much idea about js promises but i can help you with this link..
