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