For loop in multidimensional javascript array

Question

Since now, I\'m using this loop to iterate over the elements of an array, which works fine even if I put objects with various properties inside of it.

var cu         


        

Answer 1

Or you can do this alternatively with "forEach()":

var cubes = [
 [1, 2, 3],
 [4, 5, 6],    
 [7, 8, 9],
];

cubes.forEach(function each(item) {
  if (Array.isArray(item)) {
    // If is array, continue repeat loop
    item.forEach(each);
  } else {
    console.log(item);
  }
});

If you need array's index, please try this code:

var i = 0; j = 0;

cubes.forEach(function each(item) {
  if (Array.isArray(item)) {
    // If is array, continue repeat loop
    item.forEach(each);
    i++;
    j = 0;
  } else {
    console.log("[" + i + "][" + j + "] = " + item);
    j++;
  }
});

And the result will look like this:

[0][0] = 1
[0][1] = 2
[0][2] = 3
[1][0] = 4
[1][1] = 5
[1][2] = 6
[2][0] = 7
[2][1] = 8
[2][2] = 9
