Markdown (marked.js) Media Extras

I don't know how practical it is implemented, but I fork marked.js and add simple function mediaParseIdFromUrl() to parse url of YouTube, Viddler, DailyMotion and Vimeo videos and returns Video ID only. For now are only that, but if someone want can add more with simple if-else conditions.

3-media-parse-id-from-url.js

/**
 * Parse url of video to return Video ID only
 * if video exists and matches to media's host
 * else undefined
 *
 * @example mediaParseIdFromUrl('youtube', 'https://www.youtube.com/watch?v=fgQRaRqOTr0')
 * //=> fgQRaRqOTr0
 * 
 * @param  {string} provider    name of media/video site
 * @param  {string} url         url of video
 * @return {string|undefined}   the parsed id of video, if not match - undefined

    var youtubeMatch = url.match(youtubeRegex);
    if (youtubeMatch && youtubeMatch[7].length == 11) {
      return youtubeMatch[7];
    } else {
      return undefined;
    }
  } else if (provider === 'vimeo') {
    var vimeoRegex = /^.*vimeo.com\/(\d+)/;
    var vimeoMatch = url.match(vimeoRegex);
