Objects and closures are (in some ways) the same thing! (Illustrated in ES6)

objects_and_closures.js

const obj = { foo: 'bar', baz: 'quux' } // let's define our object
const { foo, baz } = bar // the keys are now in the envorinment!

const hello = 'world' // hello is defined in our environment
const newObj = { hello } // and now it's captured in our object!
