Here we have an array of `fetch(...)` promises that goes to `Promise.all`.
|
||||
|
||||
We can't change the way `Promise.all` works: if it detects an error, then it rejects with it. So we need to prevent any error from occuring. Instead, if a `fetch` error happens, we need to treat it as a "normal" result.

Once the server has responded, we can receive the result in the following properties of the request object:

|

`status`

: HTTP status code: `200`, `404`, `403` and so on. Also can be `0` if an error occured.

An `XMLHttpRequest` object travels them in the order `0` -> `1` -> `2` -> `3` -> ... -> `3` -> `4`. State `3` repeats every time a data packet is received over the network.

The example above demostrates these states. The server answers the request `digits` by sending a string of `1000` digits once per second.
