How to Sort an Array in JavaScript

How to Sort an Array in JavaScript ?

To sort an array in JavaScript, you can use the built-in sort() method.

In this example,

We create an integer array named numbers with values 5, 2, 8, 1, 6.
We use the sort() method on the array to sort it in ascending order.
The sort() method sorts the array elements in ascending order based on their UTF-16 code units values.
Finally, we print the sorted array numbers to the console.

let numbers = [5, 2, 8, 1, 6];
numbers.sort((a, b) => a - b);
console.log("Sorted array in ascending order: ", numbers);

Sorted array in ascending order:  [ 1, 2, 5, 6, 8 ]

In this example,

We create an integer array named numbers with values 5, 2, 8, 1, 6.
We use the sort() method on the array with a custom comparator to sort it in descending order.
The custom comparator sorts the array elements in descending order.
Finally, we print the sorted array numbers to the console.

let numbers = [5, 2, 8, 1, 6];
numbers.sort((a, b) => b - a);
console.log("Sorted array in descending order: ", numbers);

Sorted array in descending order:  [ 8, 6, 5, 2, 1 ]
