This is incorrect. NetworkManager's `nmcli` isn't available - by default - on many distros. The actual replacement for 'ifconfig' is in fact the iproute2 package with `ip`.
Here is the correct example, the original code should be minified to something like this:
`const double=[1,2,3].map(function(n){return 2*n});`
In the example, the savings are about 50 bytes.
