I would like to add some timeout between below get requests. I mean, flow should be looks like: `timeout, https://example.com/example1, timeout, https://example.com/example2, timeout, https://example.com/example3, timeout` etc. (or without first timeout, whatever).

Below function is working properly:

```
function promiseGetInformationFromMultipleUrls(parts) {
    return Promise.all(parts.map(part => {
      return request({
            'url': `https://example.com/${part}`,
            'json': true
        }).then(partData =>  {console.log("Part data was fetched: " + part); return partData.result;})
          .catch(err => {console.error("Error during fetching data from part: " + part + ", error code: " + err.statusCode);});
    }));
}

```

Where parts is -> example1, example2, example3....

I am trying do it by adding timer:

```
const timer = ms => new Promise( res => setTimeout(res, ms));

```

And use it:

```
function promiseGetInformationFromMultipleUrls(parts) {
    return Promise.all(parts.map(part => {
    console.log("wait 1 seconds");
    timer(1000).then(_=>console.log("done"));
      return request({
            'url': `https://example.com/${part}`,
            'json': true
        }).then(partData =>  {console.log("Part data was fetched: " + part); return partData.result;})
          .catch(err => {console.error("Error during fetching data from part: " + part + ", error code: " + err.statusCode);});
    }));
}

```

But it is wrong flow -> `timeout, timeout, timeout,..., get request1, get request 2, get request 3`.
