A Better Way to Perform Multiple Comparisons in JavaScript

Read Original

This article addresses the common problem of repetitive and hard-to-read multiple value comparisons in JavaScript (e.g., using many '||' operators). It proposes a better, more maintainable solution by storing values in an array and using the native indexOf() method to check for inclusion, making code DRYer and easier to scale.
