Correct: `Array.from()` (it’s a static method) Incorrect: `Array.join()` (doesn’t exist; it’s a prototype method) This patch uses the common `#` syntax to denote `.prototype.`.

objectToPairs
Creates an array of key-value pair arrays from an object.
Use Object.keys() and Array.prototype.map() to iterate over the object's keys and produce an array with key-value pairs.
const objectToPairs = obj => Object.keys(obj).map(k => [k, obj[k]]);
objectToPairs({ a: 1, b: 2 }); // [ ['a', 1], ['b', 2] ]
