Tell us what’s happening:

Good afternoon, I’m having trouble here, in the challenge it is explained that I have to call .repeat() on the string " " and fill it with rowCount - rowNumber. I’ve tried various ways but it still doesn’t work, please help, thank you.

Your code so far

const character = "#";
const count = 8;
const rows = [];


// User Editable Region

function padRow(rowNumber, rowCount) {
  return " " + character.repeat(rowNumber) + " ";
}

// User Editable Region


for (let i = 0; i < count; i = i + 1) {
  rows.push(padRow(i + 1, count));
}

let result = ""

for (const row of rows) {
  result = result + row + "\n";
}

console.log(result);

Hi. You have to do something similar, that you did with character variable. But don’t forget, you have two " " strings.

Sorry, can you explain in more detail?

Sure.
After return, you build a string. It starts with a number of spaces, than come a number of characters and it ends with again a number of spaces. The character is repeated correctly. Now your task is to use the same method to repeat the prefix and suffix spaces.

charToRepeat.repeat(numberOfRepetition)

You should change " " in both places.

Ahh got it, thanks bro.
