Converts a given string into an array of words.
- Use `String.prototype.split()` with a supplied `pattern` (defaults to non-alpha as a regexp) to convert to an array of strings.
- Use `Array.prototype.filter()` to remove any empty strings.
- Omit the second argument, `pattern`, to use the default regexp.
```js
const words = (str, pattern = /[^a-zA-Z-]+/) =>
str.split(pattern).filter(Boolean);
```
```js
words('I love javaScript!!'); // ['I', 'love', 'javaScript']
words('python, javaScript & coffee'); // ['python', 'javaScript', 'coffee']
```
