Script Preparation code:

function fakeBin(strNums) { 
  return strNums.split("")
                .map(num => num = num < 5 ? 0 : 1)
                .join("")
}

function fakeBin2(x) {
  return x.replace(/\d/g, n => "0000011111"[n])
}

function fakeBin3(x) {
  var result = "";
  
  for (var i = 0; i < x.length; i++) {
    if (x.charCodeAt(i) < 53) {
      result += "0";
    } else {
      result += "1";
    }
  }
  
  return result;
}
