Default parameter in function doesn't work.

[arturmaj]

On Ubuntu 17.04 , node ver.4..7.2 when I run example.js I am getting: /home/artur/google-home-notifier/google-home-notifier.js:8 var device = function(name, lang = 'en') {

                             ^

Default parameter comes with node v6. You or currently with v4.
