Tell us what’s happening:

Hello, I am having an issue with this question about “-=” operator and I am just not getting it, right now what I think is happening is correct, I think I have to change the end of the for loop from where the adding and subtraction happens. I have changed it to be “i–” to see if that would work and just “i -=1” but it is not correct, could anyone be able to drop a hint to aid me with this but not give the answer? Would greatly appreciated. When I get it right I will need to research it.

Your code so far

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

function padRow(rowNumber, rowCount) {
  return " ".repeat(rowCount - rowNumber) + character.repeat(2 * rowNumber - 1) + " ".repeat(rowCount - rowNumber);
}

// TODO: use a different type of loop
/*for (let i = 1; i <= count; i++) {
  rows.push(padRow(i, count));
}*/

/*while (rows.length < count) {
  rows.push(padRow(rows.length + 1, count));
}*/


// User Editable Region

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

// User Editable Region


let result = ""

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

console.log(result);

I fixed it, it was a complete oversight on my end, in the for loop I have it trying to be greater then “0” when it’s impossible when I am trying to invert the pyramid,

I didn’t think the condition would be an issue and ignored it, then I went back to it after a few minutes of wondering. I typed it into chat gpt trying to understand the ways I could subtract and I was even thinking now that it didn’t look right.

Came back to it and then boom it hit me. I am not great at math also so it got me pretty good.
