Combine this with arrow function syntax (which is already in Firefox):

    let square = x => x * x
 

And the next version of JavaScript is looking much more fun to work with!

Chrome also supports it if you enable Harmony

Really? I have harmony enabled in chrome://flags, but no arrow function syntax?

Hmm, I am using the Dev channel Chrome. So, it might be not in the stable (or even beta) release? It definitely worked for me when I tried it, though!
