Multi-Dimensional arrays in JavaScript

Question

Does JavaScript support multi-dimensional arrays? If so, how do I use them?

Answer 1

var arr = []; // creates a new array with dimension 1
for(a = 0; a < 10; a++) { // iterate through array (1st dim.)
arr[a] = []; // every element is assigned with a new array and arr so becomes the 2nd dimension
for(b = 0; b < 10; b++) { // iterate through 2nd dimension
arr[a][b] = a * b; // every element is filled with a value
}
}
