Thank you Majid Laissi for your answer

I made 2 functions out from your code:

the goal was to implement convertation of string to VARBINARY, BINARY and back

const stringToBinary = function(string, maxBytes) {
  //for BINARY maxBytes = 255
  //for VARBINARY maxBytes = 65535
  let binaryOutput = '';
  if (string.length > maxBytes) {
    string = string.substring(0, maxBytes);
  }

  for (var i = 0; i < string.length; i++) {
    binaryOutput += string[i].charCodeAt(0).toString(2) + ' ';
  }

  return binaryOutput;
};

and backward convertation:

const binaryToString = function(binary) {
  const arrayOfBytes = binary.split(' ');

  let stringOutput = '';

  for (let i = 0; i < arrayOfBytes.length; i++) {
    stringOutput += String.fromCharCode(parseInt(arrayOfBytes[i], 2));
  }

  return stringOutput;
};

and here is a working example: https://jsbin.com/futalidenu/edit?js,console
