The reverse() method in JavaScript is used to reverse the order of elements in an array. This method modifies the original array by reversing its elements, meaning the first element becomes the last and the last becomes the first.

The reverse() method overwrites the original array with the elements in reverse order. It does not create a new array but rather changes the existing one. This is a useful method when you need to invert the sequence of elements for tasks such as sorting in reverse order or simply changing the order for display purposes.

1. Simple Example
Here's a simple example demonstrating the use of the reverse() method:

let fruits = ["Apple", "Banana", "Cherry", "Date"]; console.log("Original array:", fruits);  // Here's i have used reverse() method fruits.reverse(); console.log("Reversed array:", fruits);  

Output:

Original array: [ 'Apple', 'Banana', 'Cherry', 'Date' ] Reversed array: [ 'Date', 'Cherry', 'Banana', 'Apple' ]  

2.Example
let's create an index.jsfile and I write code.

 var data = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];       data.reverse();       console.log(data); 

Output:
