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 cubes[]; for (i in cubes){ cubes[i].dimension cubes[i].position_x ecc.. } Now, let's suppose cubes[] is declared this way
var cubes[][]; Can I do this in JavaScript? How can I then automatically iterate in
cubes[0][0] cubes[0][1] cubes[0][2] cubes[1][0] cubes[1][1] cubes[1][2] cubes[2][0] ecc... As a workaround, I can just declare:
var cubes[]; var cubes1[]; and work separately with the two arrays. Is this a better solution?

Looping through multidimensional arrays Just as with regular, single-dimensional arrays, you can use foreach to loop through multidimensional arrays. To do this, you need to create nested foreach loops — that is, one loop inside another: The outer loop reads each element in the top-level array.
A multidimensional array is an array that contains another array. For example, // multidimensional array const data = [[1, 2, 3], [1, 3, 4], [4, 5, 6]];
JavaScript does not provide the multidimensional array natively. However, you can create a multidimensional array by defining an array of elements, where each element is also another array. For this reason, we can say that a JavaScript multidimensional array is an array of arrays.
If you just use below method to create a 3x3 matrix. Array(3). fill(Array(3). fill(0));
You can do something like this:
var cubes = [ [1, 2, 3], [4, 5, 6], [7, 8, 9], ]; for(var i = 0; i < cubes.length; i++) { var cube = cubes[i]; for(var j = 0; j < cube.length; j++) { display("cube[" + i + "][" + j + "] = " + cube[j]); } } Working jsFiddle:
The output of the above:
cube[0][0] = 1 cube[0][1] = 2 cube[0][2] = 3 cube[1][0] = 4 cube[1][1] = 5 cube[1][2] = 6 cube[2][0] = 7 cube[2][1] = 8 cube[2][2] = 9 If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
