Reinitializing Variables Inside a Loop - solution

JavaScript
1

Hi all,
I passed the challenge using a different solution than what was given. Is this still acceptable? I now know they were after using the let row variable in the for loop instead of what I did.

  **Your code so far**


function zeroArray(m, n) {
// Creates a 2-D array with m rows and n columns of zeroes
let newArray = [];
let row = [];
for (let i = 0; i < m; i++) {
  // Adds the m-th row into newArray

  for (let j = 1; j < i; j++) {
    // Pushes n zeroes into the current row to create the columns
    row.push(0,0);
  }
  // Pushes the current row, which now has n zeroes in it, to the array
  newArray.push(row);
}
return newArray;
}

let matrix = zeroArray(3, 2);
console.log(matrix);
