html - Converting Binary to text using JavaScript

Question

How can I convert Binary code to text using JavaScript? I have already made it convert text to binary but is there a way of doing it the other way around?

Here is my code:

function convertBinary() {
  var output = document.getElementById("outputBinary");
  var input = document.getElementById("inputBinary").value;
  output.value = "";
  for (i = 0; i < input.length; i++) {
    var e = input[i].charCodeAt(0);
    var s = "";
    do {
      var a = e % 2;
      e = (e - a) / 2;
      s = a + s;
    } while (e != 0);
    while (s.length < 8) {
      s = "0" + s;
    }
    output.value += s;
  }
}

I recently completed an exercise on this using a for loop. Hope it's useful:

function binaryAgent(str) {

var newBin = str.split(" ");
var binCode = [];

for (i = 0; i < newBin.length; i++) {
    binCode.push(String.fromCharCode(parseInt(newBin[i], 2)));
  }
return binCode.join("");
}
binaryAgent('01000001 01110010 01100101 01101110 00100111 01110100');
//translates to "Aren't"

EDIT: after learning more JavaScript, I was able to shortened the solution:

function binaryAgent(str) {

var binString = '';

str.split(' ').map(function(bin) {
    binString += String.fromCharCode(parseInt(bin, 2));
  });
return binString;
}
binaryAgent('01000001 01110010 01100101 01101110 00100111 01110100');
//translates to "Aren't"
