I need to replace text like ;) or :p by emoticon but I can\'t create a regex in order to detect this. Now i can detect only like :wink:

I modified AK1's answer and provided an example.

// Official Twitch robot emotes: https://twitchemotes.com
var emoticons = {
  ':)'   : 'ebf60cd72f7aa600',
  ':('   : 'd570c4b3b8d8fc4d',
  ':o'   : 'ae4e17f5b9624e2f',
  ':z'   : 'b9cbb6884788aa62',
  'B)'   : '2cde79cfe74c6169',
  ':\\'  : '374120835234cb29',
  ';)'   : '3407bf911ad2fd4a',
  ';p'   : '3407bf911ad2fd4a',
  ':p'   : 'e838e5e34d9f240c',
  'R)'   : '0536d670860bf733',
  'o_O'  : '8e128fa8dc1de29c',
  ':D'   : '9f2ac5d4b53913d7',
  '>('   : 'd31223e81104544a',
  '<3'   : '577ade91d46d7edc'
}
// Convert the emoticon map entries into their fully-qualified paths.
mapIdsToPaths(emoticons,
              'https://static-cdn.jtvnw.net/jtv_user_pictures/',
              'chansub-global-emoticon-',
              '24x18');

// Replace all possible emotes in each paragraph.
document.querySelectorAll('p').forEach(e => e.innerHTML = replaceEmoticons(e.innerHTML, emoticons));

function replaceEmoticons(text, emotes) {
   return Object.keys(emotes).reduce((result, emote) => {
      return result.replace(new RegExp(RegExpEscape(emote), 'gi'), function(match) {
        return (img => img != null ? '' : match)(emotes[match]);
      });
    }, text);
}

// helper function to escape special characters in regex
function RegExpEscape(text) {
  return text.replace(/[-[\]{}()*+?.,\\^$|#\s]/g, "\\$&");
}

// Map emote ids to their URLs.
function mapIdsToPaths(emotes, url, prefix, size) {
  Object.keys(emotes).forEach((id) => {
    emotes[id] = url + prefix + emotes[id] + '-' + size + '.png';
  });
}

Hello ;)
