“process.env” is your access to the shell environment. On a *nix system,
process.env.X provides you the value of the environment variable X, if it is
set. In the line of code above, it appears that the value for the port the
server is to use is determined by what the user has set in the “Port”
environment variable, with a fallback value of 3000. There is no special
meaning to process.env.Port, AFAIK, in Node or Express.
