Tell us what’s happening:

Can anyone tell me whats wrong why isnt the .shift method working?

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));
}*/

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


// User Editable Region

const numbers = [1, 2, 3];


const unshifted = numbers.unshift(5);
console.log(unshifted);
console.log(numbers);
const shifted = numbers.shift();
console.log(shifted)  

// User Editable Region


let result = ""

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

console.log(result);

Hi there,

You’re on the right track — your code is correct, but it’s not placed where the lesson expects it to be.

Lesson says:

Directly below your numbers array, declare a shifted variable and assign it the result of calling .shift() on the numbers array. On the next line, log the shifted variable to the console.

So just move those two lines. And it will pass
