new feature proposal: default value if var is not defined

how can I make sure that if an environment variable is not defined(inside .env file) I can have a default value? example: assuming that the PORT variable is not specified in my .env file but I want to have a default value anyway:

require('dotenv').config({
  defaults: {
    PORT: 8080
  }
})

Looks good! If approved, I would like to work on the issue.

@tawfiek I think your team will like it. It makes it very easy to securely sync you .env files across your team’s many machines. So far everyone using it so far is really enjoying it. They say it is like using git - one of the first things they now reach for with their team.
