Web Reference: This tutorial shows you how to effectively create JavaScript multidimensional arrays using an array of arrays. Jul 12, 2025 · JavaScript does not have built-in support for multidimensional arrays like some other programming languages, but you can simulate them using nested arrays. This approach allows you to work with grids, matrices, or even higher-dimensional data structures. In JavaScript 1.7 and higher you can use array comprehensions to create two dimensional arrays. You can also filter and/or manipulate the entries while filling the array and don't have to use loops.
