I don’t get it. Can someone Explain Like I’m 5?

There is a function that always returns false, and then a bunch of random output, and one failed?

Is this like another weird quirk in the JavaScript VM or something? Lol?

Prime numbers become less frequent as the numbers get larger, so if you want to implement a function that tests whether a number is prime, just always returning false will get more and more accurate as you count up. The console output is just saying whether it was correct to say the number isn't prime, and the percent is the accuracy over the previous numbers
