Not going to comment about Go here but JavaScript code like what is written above confuses many people. `Promise`s begin to resolve immediately on creation whether or not we've attempted to unwrap their value using `await`.

Therefore, it's quite possible that the first call to `promise()` might resolve after 3 seconds, while the next two calls could take 7 seconds and 10 seconds respectively. In this case, the `Promise.all` would produce a result after 10 seconds, and then the next line `const a = await aPromise` would unwrap the value within `aPromise` immediately as it would already have been fulfilled 3 seconds into the `await Promise.all([promise(), promise()])`.
