Recursion-1.js

// Given this Object
const obj1 = {
  one: 1,
  two: 2,
  three: { four: 4, five: { six: 6 } },
  seven: 7,
  eight: { nine: 9, ten: 10 },
  eleven: { twelve: { thirteen: { fourteen: 14 } } },
};

// It should return a one dimensional Object, with all of the nested key-value pairs
{ one: 1, two: 2, four: 4, six: 6, seven: 7, nine: 9, ten: 10, fourteen: 14 }
