Computed property names allows an expression to compute the name of a
property, both in classes and object literals.

let object = {
[40 + 2]: 'meaning?'
};

The main use case for these are for using symbol keys as property names.

class Iterable {
*[Symbol.iterator]() { yield 1; yield 2; }
}

The ES6 spec is currently RC1. [1]

Mozilla shipped this in Firefox 34.

Internet Explorer support is in their current Preview Release [3].
