How to push with a multidimensional array with JavaScript?

To push an element to a multidimensional array in JavaScript, you can use the Array.push() method on the outer array to add a new inner array containing the element.

Here’s an example:

let array = [[1, 2], [3, 4]];
array.push([5]);
console.log(array); // [[1, 2], [3, 4], [5]]

In this example, we create a multidimensional array array with two inner arrays. To add a new element to the outer array, we use the Array.push() method to add a new inner array containing the element 5. The resulting array is then logged to the console.
