Would you like to build a function?

looksay.js

// Hey Anna, wanna write a function that returns the output for a look and say sequence: https://en.wikipedia.org/wiki/Look-and-say_sequence

function lookAndSaySequence(n) {

  // would you like to build a function?
  // a function that returns a striiiing. 
  var lookSay = function(strNum) {
    var sayArray = [];
    var repeats = 1; // we check to see how many nums
    var digit = 0; // and say the num
    for (var i = 0; i < strNum.length; i++) {
      if (!!strNum.charAt(i + 1) && strNum.charAt(i) === strNum.charAt(i +
        1)) { // and if they are the saaaaaame?
        repeats++; // if they are we take this, and increment
      } else {
        digit = strNum.charAt(i); // else digit is the char at IIIIII!
        sayArray.push(repeats);
        sayArray.push(digit);
        repeats = 1;
      }
    }
    return sayArray.join(""); // would you like to build a function.
    // a for-loop non-recursive function... 
  };
  // okay, bye. 

  var output = ''; // Would you like to have an output!
  // have an output as a striiiing. 
  for (var i = 1; i <= n; i++) { // and now we're going to iterate
    // say, ain't it great, we can count up to the thiiiing!
    if (i === 1) {
      output = '1'; // here we have our edge case.
      // when i is 1
      // and build from there to the sky!!!!
    } else {
      output = lookSay(output); // then we iterate the output... 
    }
  }
  // a stringy super-awesome output!
  return output;
