Hey all, I thought it about time I introduced you all to NaN ;). So in this JavaScript tutorial for beginners I’ll be showing you what NaN is (Not a Number) and how we can use it to check whether certain variables are indeed a number or not.
As usual, ask away with any questions you have :).

Really liked the "ain't" to "int" pun there, keep the lessons amusing and interesting 🙂
Great tutorial man. Quick question, Why do we need to use isNaN()? Why can't we just check if the variable is an int?
