Convert function from ActionScript to Javascript

Question

I receive a get request from server, but is encrypted with a simple algorithm in Python, so I have this Method in ActionScript for decrypt this :

public static function Decrypt (encrypted : String) : String { var resultArray : ByteArray = new ByteArray(); for (var i:int = 0; i < encrypted.length; i++){ resultArray.writeByte(encrypted.charCodeAt(i) ^ 0x34); } var resultString : String = resultArray.toString(); return resultString; }

Now, I need to implement this function in Javascript, but there is no ByteArray class in JS, any idea of how i can do this? Code and librarys are welcome.

 function Decrypt(encrypted) {
    var resultString = '';
    for (var i = 0; i < encrypted.length; i++) {
        resultString += String.fromCharCode(encrypted.charCodeAt(i) ^ 0x34);
    } 
    return resultString;
 }

Try something like this:

function Decrypt(encrypted) {
    var resultString = '';
    for (var i = 0; i < encrypted.length; i++) {
        resultString += (encrypted[i] ^ 0x34);
    } 
    return resultString
}

why the post was downvoted? If you don't tell I can't improve the answer.

the typo was corrected. Don't work how? Is there is any error message? Can't test without some sample data...

Missed String.fromCharCode function, that's the detail, check @Diode answer

Just replace it with a normal JS array ( [] ) and change resultArray.writeByte to resultArray.push. Also make resultArray.toString() into resultArray.join(''). All the rest of the code should work as is (assuming you drop things like public static, : String, :int, etc that aren't valid in JS)

What about the writeByte function? Should I use push instead?
