Return the provided string with the first letter of each word capitalized. Make sure the rest of the word is in lower case.
|
|
|

For the purpose of this exercise, you should also capitalize connecting words like `the` and `of`.

assert.isString(titleCase("I'm a little tea pot"));
|
|
```
|

|
|
|
|
```js
|
|
assert.strictEqual(titleCase("I'm a little tea pot"), "I'm A Little Tea Pot");
|
|
```
|
|
|
|

|
|
assert.strictEqual(titleCase('sHoRt AnD sToUt'), 'Short And Stout');
|
|
```
|

titleCase('HERE IS MY HANDLE HERE IS MY SPOUT'),
