# Reverse order of Multidimensional Array

2

I need to invert the positions of an Array, where the first pass to the last the second to the penultimate and so on.

For example, I have a 3-position Array:

``````[1,1.00,2300]
[2,1.00,4500]
[3,1.00,2340]
``````

and this should be your result:

``````[3,1.00,2340]
[2,1.00,4500]
[1,1.00,2300]
``````

Thanks !!!

There are different ways to modify the order of an array as `sort()` (sort alphabetically or numerically [ modifying it a little], ascending or descending) , `reverse()` (reverses the order of an array by sending the first position to the last and so on) , ...

## REVERSE

Summary

The `reverse()` method reverses (inversely) a matrix. The first element becomes the last and the last becomes the first.

Syntax

arr.reverse ()

Description

The `reverse` method crosses the elements of the parent object invoked instead, by mutating the array, and returning a reference to it.

Examples

The following example creates a matrix myMatrix, contains three elements, these are placed upside down (inversely) in the matrix.

``````var miMatriz = [[1,1.00,2300],[2,1.00,4500],[3,1.00,2340]];
var invertida = miMatriz.reverse();

console.log(miMatriz);
console.log(invertida);``````
