In JavaScript, you can do basic object assignment like this:
const obj = { one : 1, two : 2 }
let one = obj.one
let two = obj.two
However, with ES6 you can assign the variables in a much more succinct way. Use ES6 object destructuring to assign variables one and two to obj.one and obj.two respectively.
Although you can use let, var, or const for assignment, DO NOT use these in this challenge.
