+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']
+```
