--description--

Again, push the result of calling padRow with your i and count variables to your rows array.

Open up the console to see the upside-down pyramid.

--hints--

Your for loop should call rows.push().

js
assert.match(__helpers.removeJSComments(code), /for\s*\(\s*let\s+i\s*=\s*count\s*;\s*i\s*>\s*0\s*;\s*i\s*=\s*i\s*-\s*1\s*\)\s*\{\s*rows\.push\(/);

You should call padRow() in your .push() call.

js
assert.match(__helpers.removeJSComments(code), /for\s*\(\s*let\s+i\s*=\s*count\s*;\s*i\s*>\s*0\s*;\s*i\s*=\s*i\s*-\s*1\s*\)\s*\{\s*rows\.push\(\s*padRow\s*\(/);

You should pass i as the first argument to your padRow() call.

js
assert.match(__helpers.removeJSComments(code), /for\s*\(\s*let\s+i\s*=\s*count\s*;\s*i\s*>\s*0\s*;\s*i\s*=\s*i\s*-\s*1\s*\)\s*\{\s*rows\.push\(\s*padRow\s*\(\s*i/);

You should pass count as the second argument to your padRow() call.

js
assert.match(__helpers.removeJSComments(code), /for\s*\(\s*let\s+i\s*=\s*count\s*;\s*i\s*>\s*0\s*;\s*i\s*=\s*i\s*-\s*1\s*\)\s*\{\s*rows\.push\(\s*padRow\s*\(\s*i\s*,\s*count\s*\)\s*\)/);

js
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));
}*/
