Sometimes it is useful to route traffic through a different machine for testing or development. At work, we have a VPN to a remote facility that we haven't bothered to fix for routing, so the only way to access a certain machine over that VPN is via an SSH tunnel to a machine that is reachable over the VPN. Other times, I have used this technique to test internet-facing requests against sites I am developing. It is pretty easy, and if you don't use firefox regularly, you can treat Firefox as your "Proxy" browser and other browsers can use a normal configuration (Although you can also configure an entire system to use the proxy, other articles exists that discuss this potential).

Group Array of JavaScript Objects by Key or Property Value

Implementation

const groupBy = key => array =>
  array.reduce((objectsByKeyValue, obj) => {
    const value = obj[key];
    objectsByKeyValue[value] = (objectsByKeyValue[value] || []).concat(obj);
    return objectsByKeyValue;
