Tell us what’s happening:
I have consoled logged and got a problem as follow
Can anyone tell me when the variable i =1 then the value of newArray is [[0,0,0,0] [0,0,0,0]]
on output. I think the value of newArray should be [[0,0],[0,0,0,0]]
.
If i am wrong please correct me
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);
console.log("At pass "+j+ ": ");
console.log(row);
console.log("After row
");
}
// Pushes the current row, which now has n zeroes in it, to the array
newArray.push(row);
console.log("
At pass "+i+ ": ");
console.log(newArray);
console.log("after col
")
}
return newArray;
}
let matrix = zeroArray(3, 2);
console.log(matrix);
