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. Use Array.filter() to remove any empty strings. Omit the second argument to use the default regex.

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"]
