See the following example of multi-dimensional array in javaScript; as shown below:

var arr = [
     ['php', 'python', 'perl'],
     ['xampp', 'mysql', 'sql'],
     ['jquery', 'javaScript', 'angular', 'react']
 ];

Here, i will create an example for access items from multidimensional array; as shown below:

document.write(arr[1][1]);

// output

// mysql

The JavaScript array index starts with zero. The first bracket refers to the desired item in the outer array. The second bracket refers to the desired item in the internal array.

arr[1].push('native', 'laravel');

Here we use the javascript array push method to add two new elements(items) to the inner sub-array.

Add a new array of multidimensional array :

arr.push( ['testing', 'rust', 'c'] );
