JavaScript Masterclass - Zero to Job-Ready with Hands-On Projects - Null and Undefined / 014

This lecture explains the concepts of null and undefined in programming. Null is an intentional assignment of emptiness to a variable, while undefined indicates a variable has been declared but not assigned a value. Examples demonstrate how null and undefined behave differently in operations and functions. Null is useful for resetting values or indicating intentional emptiness, whereas undefined can lead to errors if used in operations. Understanding these concepts is crucial for effective programming.
