How to get a subset of a javascript object's properties

Say I have an object: elmo = { color: 'red', annoying: true, height: 'unknown', meta: { one: '1', two: '2'} }; I want to make a new object with a subset of its properties. // pseudo code subset = elmo.slice('color', 'height') //=> { color: 'red', height: 'unknown' } How may I achieve this?
