Hello,
I dont understand the base of the problem. it says the function creates m rows and n columns, meaning we should have m rows while it only has 1 row but m subarrays. does not make any sense to me.
please advise.
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
row=[]
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);

No, we have exactly n columns.
Lets modify function you posted:

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
row=[]
for (let j = 0; j < n; j++) {
// Pushes n zeroes into the current row to create the columns
row.push(String(i) + ',' + String(j));
}
// 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);
/* OUTPUT
[ [ '0,0', '0,1' ],
[ '1,0', '1,1' ],
[ '2,0', '2,1' ] ];
*/

I changed some stuff - actually just one line - where we pushing elements in subarrays
so now you can see that every element of every sub array represents one specific element of matrix,
and every element has two , you can say, coordinates -
first coordinate represents row,
second coordinate represents column
