To create a Three Dimensional Array in JavaScript, you can use nested arrays or Array constructor with specified dimensions.
In this example,
// Creating a 3D Array with Nested Arrays
let threeDArray = [[[0, 0, 0, 0], [0, 0, 0, 0]], [[0, 0, 0, 0], [0, 0, 0, 0]], [[0, 0, 0, 0], [0, 0, 0, 0]]];
// Accessing and modifying elements
threeDArray[1][0][2] = 5;
// Printing the array
console.log(JSON.stringify(threeDArray));
[[[0,0,0,0],[0,0,0,0]],[[0,0,5,0],[0,0,0,0]],[[0,0,0,0],[0,0,0,0]]]
In this tutorial, we learned How to create a Three Dimensional Array in JavaScript language with well detailed examples.
