**Tell us what’s happening:**

The problem for this exercise is instead of [[0,0],[0,0],[0,0]], myArray turns out to be

[ [ 0, 0, 0, 0, 0, 0 ],

[ 0, 0, 0, 0, 0, 0 ],

[ 0, 0, 0, 0, 0, 0 ] ]

I don’t understand why myArray is [ [ 0, 0, 0, 0, 0, 0 ],

[ 0, 0, 0, 0, 0, 0 ],

[ 0, 0, 0, 0, 0, 0 ] ]

in my reasoning, since row is updated every time, newArray should be [[0,0], [0,0,0,0], [0,0,0,0,0,0]

*Just to be clear, I’m not asking about the explanation of the solution.

Plese help. Thanks!

**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 = 0; j < n; j++) {
// Pushes n zeroes into the current row to create the columns
row.push(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);
```
