Does node.js support the 'let' statement?

Question

Does node.js support a let statement something like what\'s described on MDN??

var x = 8,
    y = 12;

let ( x = 5, y = 10) {
    return x + y;
} //15

You can use the Babel transpiler and use let as well as many other ES6/ES2015 features.

To use babel:

$ npm install --save-dev babel

Then in your package.json:

"scripts": {
  "start": "babel-node index.js"
}

Inside index.js:

let foo  = 'bar;

Then start the server:

$ npm start
