This function will replace any words you want in a string.

function wordInString(s, words, replacement){ 
  var re = new RegExp( '\\b' + words.join('|') + '\\b','gi');
  return s.replace(re, replacement);
}

// usage:
var str = 'did you, or did you not, get why?';
str = wordInString(str, ['YOU', 'get'], 'XXX');

console.log(str); // "did XXX, or did XXX not, XXX why?"
