Using ECMAScript 6 In Node.JS

Question

I'm sure this is a simple one - But I'm learning Javascript and executing programs through Node.js

function sumAll(arr) {

   var max = Math.max(...arr);
   console.log(max);

}

sumAll([1, 4]);

The error I have is:

SyntaxError: Unexpected token ...

I assume this is down to the ES6 spread operator? Is this not valid?

I have also tried to add the following, based on other StackOverflow answers I've found:

"use strict";

But this doesn't work either.

Any help appreciated - Thanks

FYI, `...` [is not an operator](http://stackoverflow.com/a/37152508/218196). — Felix Kling, Oct 31 '16 at 14:40
@FelixKling - How should I refer to "..." when speaking with other developers? — Andrew Birks, Oct 31 '16 at 15:03

Seems that you use outdated node.js version. Try to update your node.js to the latest version.

Might be you are using outdated node.js version. Try to update your node.js with v6.10 or later on the latest version.
