JavaScript Regex to create array of whole words only.

I'm trying to split out the whole words out of a string without whitespace or special characters.

So from 

'(votes + downvotes) / views'

I'd like to create an array like the following

['votes', 'downvotes, 'views']

Have tried the following, but catching the parens and some whitespace. https://regex101.com/r/yX9iW8/1

It's very simple...

var matches = '(votes + downvotes) / views'.match(/[a-z]+/ig);

You must decide for your project what characters make a words, and min-length of word. It can be chars with digits and dash with min-length of 3 characters... 

[a-z0-9-]{3,}

Good luck!

You could use /\w+/g as regular expression in combination with String#match

var array = '(votes + downvotes) / views'.match(/\w+/g);
console.log(array);

You can use \W+ to split on all non-word characters

'(votes + downvotes) / views'.split(/\W+/g).filter(x => x !== '');
// ["votes", "downvotes", "views"]

Or \w+ to match on all word characters

'(votes + downvotes) / views'.match(/\w+/g);
// ["votes", "downvotes", "views"]
