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 to use the default regexp.

const words = (str, pattern = /[^a-zA-Z-]+/) => str.split(pattern).filter(Boolean);

words('I love javaScript!!'); // ["I", "love", "javaScript"]
words('python, javaScript & coffee'); // ["python", "javaScript", "coffee"]
