Am I missing steps on Binary Agents?

JavaScript

Tell us what’s happening:

I’m not passing any tests and I’m returning nothing but question mark symbols or empty character boxes. I’m not exactly sure what step I’m missing because I think I have a logical setup. (Transform into array, loop through and convert to integer then to alphabet equivalent of that integer.)

My ideas:

  1. It’s HOW I’m doing it. But I don’t know how my method is inappropriate.
  2. I should be using something else instead of parseInt(). I tried charCodeAt() and it only returned binary so I tried parseInt. I also think I’m missing a step, but I think I’ve taken care of all necessary conversions…

Your guidance would be much appreciated.

Thank you.

Your code so far


function binaryAgent(str) {
 //global variable
 let final = [];
 let add = [];
 //transform string into an array
 let neu = str.split('');
//loop through new array and transform each element into an integer using parseInt with base-2 in order to convert from binary
  for(let i = 0;i < neu.length; i++){
    add.push(parseInt(neu[i], 2));
  //Convert from UTF integer to alphabet symbol
    final.push(String.fromCharCode(add[i]))
    console.log(final)
  }
  
  return final;
}

binaryAgent("01000001 01110010 01100101 01101110 00100111 01110100 00100000 01100010 01101111 01101110 01100110 01101001 01110010 01100101 01110011 00100000 01100110 01110101 01101110 00100001 00111111");

You are splitting on an empty string so you will have a character per array element - you may want to split on a space instead so you have a number per array element

After that we can recheck if the logic is sound (it should be)

function binaryAgent(str) {
  console.log(str)
 //global variable
 let final = [];
 let add = [];
 //transform string into an array
 let neu = str.split(' ');
 console.log(neu)
//loop through new array and transform each element into an integer using parseInt with base-2 in order to convert from binary
  for(let i = 0;i < neu.length; i++){
    add.push(parseInt(neu, 2));
  //Convert from UTF integer to alphabet symbol
 let final = String.fromCharCode(add[i]);
  }

  
  
  return final;
}

binaryAgent("01000001 01110010 01100101 01101110 00100111 01110100 00100000 01100010 01101111 01101110 01100110 01101001 01110010 01100101 01110011 00100000 01100110 01110101 01101110 00100001 00111111");

I’m not passing the test. Not sure why. But if I had to guess, I think that I don’t need to use add, but my reasoning is that I wanted to have a clean, empty array that I could push the binary-converted-to-integer elements into.
Is my issue that I have too much in the code and that I need to simplify it or is everything in the correct order and the logic sound but my syntax is a little off or perhaps I don’t fully understand what the syntax is doing and so have given methods the wrong kind of perimeters or set conditions that are not appropriate.

Thanks for any kind of nudge.
