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.`.

objectFromPairs
Creates an object from the given key-value pairs.
Use Array.prototype.reduce() to create and combine key-value pairs.
const objectFromPairs = arr => arr.reduce((a, [key, val]) => ((a[key] = val), a), {});
objectFromPairs([['a', 1], ['b', 2]]); // {a: 1, b: 2}
