JavaScript Multidimensional Array

A multidimensional array in JavaScript is an array that contains one or more arrays as elements. These arrays can be thought of as matrices where each array element represents a single value and each row or column represents a single dimension.

Arrays in JavaScript are usually one-dimensional. That is, there is only one element level. However, nesting arrays allows you to create multidimensional arrays.

Here is an example of a javascript multidimensional array

let matrix = [

[1, 2, 3],

[4, 5, 6],

[7, 8, 9]

];

Example:

var fruits1 = [ ["apple", "red", "sweet"], 

["banana", "yellow", "tropical"], 

["orange", "orange", "citrus"] ];

// accessing the first fruit's properties 

console.log("The " + fruits1[0][0] + " is " + fruits1[0][1] + " and " + fruits1[0][2] + ".");




// updating a fruit's property 

fruits1[1][1] = "brown";




// adding a new fruit to the array 

fruits1.push(["grape", "purple", "juicy"]);




// looping through the array and displaying each fruit's properties 

for (var j = 0; j < fruits1.length; j++) 

{ 

console.log("The " + fruits1[j][0] + " is " + fruits1[j][1] + " and " + fruits1[j][2] + "."); 

}

Output:

The apple is red and sweet.

The banana is brown and tropical.

The orange is orange and citrus.

The grape is purple and juicy.
