我该如何修改这个 function

Question

I modify this function but I want to be sure this is right because it suppose to take me to the next code question but it didn't even after it printed the result as correct.

Modify this Function to return avg

function getAverageTestScore(scores) {
  let testScores = (scores[0] + scores[1]) / 2
  return testScores;
}

/* Do not modify code below this line */
const avg = getAverageTestScore([80, 100]);
console.log(avg, '<-- should be 90');

Answer 1

Try this function, it will accept unlimited number of inputs and return average of them

 function getAverageTestScore(...scores) { let result = 0; for(let score of scores) { result += score; } return result / scores.length; } let avg = getAverageTestScore(2, 2, 2); console.log(avg) // 2

Answer 2

The scorer is probably running your function with some other inputs, so you probably need to modify it to accept arrays with length other than 2. Use a loop to sum the values, then divide by the number of elements.
