If you're retrieving this data in JSON format, the response should be an array. For example, you could log all the "avg_signal" values in the first element to the console this way:

for (var req of response[0].probe_requests)
  console.log(req.avg_signal);

you can use the eggs array, the array returning from the eggs function and run this

eggs.map(item => item.probe_requests)[0].reduce((result, currVal) => { result.push(currVal.avg_signal); return result; }, []);
