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