Learn Introductory JavaScript by Building a Pyramid Generator - Step 103

Tell us what’s happening:

In step 103 it says, replace your iteration statement with the correct statement using the subtraction assignment operator. I did it in Code.io and it works; does it not work here? Rolling my eyes! ugh!
for (let i = count; i > 0; i -= 1) {
rows.push(padRow(i, count));
}

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 + row + "\n";
}

console.log(result);

Hi

Correct use of the assignment operator should make it shorter than this:

i = i -= 1)

See the syntax here: JavaScript Assignment

The code above was posted in your description, but this code was picked up by HELP:

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

See the difference?
