Convert JavaScript data structures

const obj = {

  a: 1,

  b: 2,

  c: 3

};

​

// All of the below are now an array,

// you can use all the array methods and properties, 

// e.g. .reduce or .length

const keys = Object.keys(obj); // ['a', 'b', 'c']

const values = Object.values(obj); // [1, 2, 3]

const entries = Object.entries(obj); // [["a", 1], ["b", 2], ["c", 3]]
