Tell us what’s happening:

I keep being told my function needs to return a number. I have run this code through other javascript console simulators and it returns the correct number as specified by the. What is the issue with my code?

Your code so far


// User Editable Region

function getAverage(scores) {
  let sumTotal = 0;
  let average = 0;
  for ( i = 0; i < scores.length; i++) {
    sumTotal = sumTotal + scores[i];
  }
  average = sumTotal / scores.length;
  return average;
}

console.log(getAverage([92, 88, 12, 77, 57, 100, 67, 38, 97, 89]));
console.log(getAverage([45, 87, 98, 100, 86, 94, 67, 88, 94, 95]));

Yeah, I’ve tried to correct that and it still didn’t work. Also, I just went ahead to the next step and tried copying in the answer there, and it still said the code didn’t work. I think something has gone wrong with the JS console on the website.

When I reload the page, this message appears in the console:

ChunkLoadError: Loading chunk 155 failed.
(missing: https://www.freecodecamp.org/@babel/standalone-44c7f8d4c36bc54a66fc.js)

Is there a missing library or dependency or something?

What is your code when you fix your bug with i? I can’t see what’s happening if you don’t share your fixed code. The Step works correctly when write I correct code.

Yeah, there was an error with the webpage itself. The cache had some sort of an error and the JS console engine was not loading properly. I cleared the cache and re-logged in and the problem was resolved.

You should not copy-paste other people’s answers, no
