Handling Null, Undefined and Zero Values in JavaScript

Read Original

This JavaScript tutorial discusses common pitfalls when checking for null, undefined, and zero values. It explains why using `!!value` or the `||` operator can incorrectly filter out zero, and demonstrates better approaches like type checking and using the nullish coalescing operator (`??`) to provide accurate default values.
