Can methods be defined in an object initializer without using the `function` keyword?

Question

The other day I was a bit tired, I wrote this JavaScript code:

var obj = {a(toto){console.log(\"func a: \", toto);} };

This is ECMAScript 6 syntax. Depending on your environment - node vs browser - it may or may not be advisable to use this syntax (e.g. not supported cross browser).

Given the following code:

var obj = { foo: function() {}, bar: function() {} };

You are now able to shorten this to:

var obj = { foo() {}, bar() {} };
