03. Undefined vs Null vs Not Defined | Interview Question | JS Pro Series

Js Pro Series will be a comprehensive in-depth JavaScript Course that will cover all concepts from the fundamentals to the advanced. It will cover all of the fundamental concepts while also teaching you how to apply that conceptual knowledge to actual projects and codes.

In this video, we will go over our first interview question. We will learn the difference between Undefined, Not defined and Null. Interviewers are more likely to ask about these three concepts together than separately, so we'll learn about them in this short video.

Save this Playlist so you don't miss any videos.

This series will concentrate on laying out a precise and structured method of teaching JavaScript concepts, so you don't get confused. We'll attempt to explain how those concepts are used or applied in real-world projects and codes.
After finishing the beginner and intermediate levels of this course, we will release the advanced series, which will cover interview questions and advanced topics for a better understanding. This course will be completely free, with new videos added every week.

We would love to connect with you!
