What are some common array sorting techniques in JavaScript?

In JavaScript, common array sorting techniques include using the built-in sort() method, implementing bubble sort, merge sort, and quicksort.

Can you explain how the sort() method works?

Sure! The sort() method sorts the elements of an array in place and returns the sorted array. By default, it sorts elements as strings. You can provide a compare function to customize the sorting order.

What is a compare function?

A compare function is a function that defines the sort order. It takes two arguments and returns a negative number, zero, or a positive number, depending on the desired order of the elements.

Can you give me an example of a compare function?

Certainly! Here's a simple example: array.sort((a, b) => a - b); This sorts the array in ascending numerical order.
