// FIRST PASS

// remove scripts
words = words.replace(/[\s\S]*?<\/script>/gi, '');
// remove CSS
words = words.replace(/[\s\S]*?<\/style>/gi, '');
// remove comments
words = words.replace(//g, '');
// remove html character entities
words = words.replace(/&.*?;/g, ' ');
// remove all HTML
words = words.replace(/<[\s\S]*?>/g, '');

// SECOND PASS

// remove all newlines
words = words.replace(/\n/g, ' ');
// replace multiple spaces with 1 space
words = words.replace(/\s{2,}/g, ' ');

// split each word
words = words.split(/[^a-z-']+/gi);
