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.`.

lowercaseKeys
Creates a new object from the specified object, where all the keys are in lowercase.
Use Object.keys() and Array.prototype.reduce() to create a new object from the specified object.
Convert each key in the original object to lowercase, using String.toLowerCase().
const lowercaseKeys = obj =>
Object.keys(obj).reduce((acc, key) => {
acc[key.toLowerCase()] = obj[key];
return acc;
}, {});
const myObj = { Name: 'Adam', sUrnAME: 'Smith' };
const myObjLower = lowercaseKeys(myObj); // {name: 'Adam', surname: 'Smith'};
