Does a youtube video have a scrambled signature or not?

yt-sig.js

function parse(query) {
    const allpairs = query.split("&");
    const out = {};
    for (let i = 0; i < allpairs.length; i++) {
      let pair = allpairs[i].split("=");
      let key = pair[0];
      let val = pair[1];
      out[key] = val;
    }
  return out;
}

function hasScrambledSignature() {
  const info = ytplayer.config.args.adaptive_fmts.split(",");
  const stream = parse( info[0] );
  if (stream.s) {
    return true;
  }
  else {
    return false;
  }
}

console.log( hasScrambledSignature() );
