var bytes = [84,104,105,115,32,105,115,32,97,32,115,97,109,112,108,101,32,112,97,114,97,103,114,97,112,104,46];
var bufferArray = new Uint16Array(bytes);
var decoder = new TextDecoder('utf8'); // default 'utf-8' or 'utf8'
​
Tests:

  • String.fromCharCode

     
    String.fromCharCode.apply(null, bufferArray);

  • TextDecoder

     
    decoder.decode(bufferArray);
