Tell us what’s happening:

hi there
can you plz help me where should i apply -=
??!

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);

Use the subtraction assignment operator -= instead of the = operator between the existing i and the right side of the equality operator. The right side should only contain the value that should be subtracted.

Thank you for your help with this DobarBREND.

Being an absolute noob, I don’t want to presume I know better than whoever put this together, but… the instructions are to replace the ‘iterator statement’, which is the: ‘let i = count’ section of the for statement isn’t it?

This is what confused me.

Thanks again.
