+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
+let myObj = {Name: 'Adam', sUrnAME: 'Smith'};
+let myObjLower = lowercaseKeys(myObj);
+console.log(myObj); // {Name: 'Adam', sUrnAME: 'Smith'};
+console.log(myObjLower); // {name: 'Adam', surname: 'Smith'};
+```
