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.

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']
