This article I am going to show you the different way you can reverse an Array.
Array is a group of similar item, number etc that is store in single variable. For eg: let arr1 = [1,2,3]; This is an array example with a group of numbers.
There are multiple ways we can reverse an Array. One of the most easy way to do is to using array methods.
let x = [1,2,3,4,5,6];
let reverseX = x.reverse(); // prints [6, 5, 4, 3, 2, 1]
let x = [1,2,3,4,5,6];
let Xlen = x.length;
for(let i=0; i<n/2); i++){
let startIndex = i;
let endIndex = n-1 - i;
let temp = a[endIndex];
a[startIndex] = a[endIndex];
a[endIndex] = temp;
}
console.log(x); // [6,5,4,3,2,1]
