How to create multidimensional array with JavaScript?

To create multidimensional array with JavaScript, we can use a for loop.

For instance, we write

let row = 20;
let column = 10;
let f = new Array();

for (i = 0; i < row; i++) {
  f[i] = new Array();
  for (j = 0; j < column; j++) {
    f[i][j] = 0;
  }
}

to create a nested for loop that adds the nested arrays to the f array with the outer loop.

In the inner loop, we fill the nested arrays with 0’s with

for (j = 0; j < column; j++) {
  f[i][j] = 0;
}

Conclusion

To create multidimensional array with JavaScript, we can use a for loop.
