array.sort() Does Not Simply Sort Numbers in JavaScript

Read Original

This article details a common JavaScript pitfall: the default array.sort() method converts numbers to strings and sorts them alphabetically, leading to unexpected results like [10, 11, 5]. It explains how to correctly sort numbers by providing a comparator function, such as (a, b) => a - b, and briefly mentions typed arrays as an alternative.
