JavaScript Introducing ES2015 The Cooler Parts of ES2015 Default Parameters

Why am I getting this error in the console?

$ node default-parameters.js
C:\Users\Rusie\Documents\susan_treehouse\Introducing_ES2015\Default_Parameters\s
tart\default-parameters.js:3
function greet(name = 'Guil', timeOfDay = 'Day') {
                    ^

SyntaxError: Unexpected token =
    at exports.runInThisContext (vm.js:53:16)
    at Module._compile (module.js:373:25)
    at Object.Module._extensions..js (module.js:416:10)
    at Module.load (module.js:343:32)

    at Function.Module.runMain (module.js:441:10)
    at startup (node.js:139:18)
    at node.js:968:3

Here is my code:

'use strict';

function greet(name  =  'Guil',  timeOfDay  =  'Day') {
  console.log(`Good ${timeOfDay}, ${name}!`);
}

greet(undefined, 'Afternoon');

I have played around with the spacing on that line, but I still get the same error. What am I doing wrong?

This code also works for me when copy-pasted into my own file with zero edits. I am using node v6.9.2.

Rogier, Updating Node is what was needed. Everything is now working as it should. Thanks for your help.
