number 1 is removed, where is the problem ?

const numbers = [1, 2, 3];
numbers.shift();
const shifted = numbers;
console.log(shifted);

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];
numbers.shift();

const shifted = numbers;

console.log(shifted); 



let result = ""

for (const row of rows) {

// User Editable Region

  result = result + "\n" + row;
}

console.log(result);

Hi there,

The intruction said:

declare a shifted variable and assign it the result of calling .shift() on the numbers array

that means we need to assign the value returned from the call: numbers.shift() to shifted.

What you did was assign the array numbers to shifted:
