What is the output of the following code snippet? console.log(typeof null); console.log(typeof undefined);

Accepted Answer

In JavaScript, 'typeof null' returns 'object' due to a long-standing historical bug in the language implementation. 'typeof undefined' correctly returns 'undefined'. This is a fundamental quirk of JavaScript's type system that developers must account for when performing type checks.
