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?
