What is the difference between Promise.all and Promise.allSettled?

Do you know what will be the output of this code?

JavaScript

Promise.allSettled([Promise.resolve(1), Promise.reject(2)])
  .then((results) => console.log(results.map((r) => r.status)));

Show answer and explanation

The answer is ["fulfilled", "rejected"].

allSettled resolves with one object per promise: { status: "fulfilled", value } or { status: "rejected", reason }. It never rejects itself.
