What is a Predicate Function? JavaScript & Haskell Examples

Thanks for watching this video! If you learned something, like the video. If you have more questions or feedback, leave a comment in the description. In this video, I explain predicate functions -- what they are, and where you'll use them. Most of the examples are in JavaScript, but I show the Haskell syntax for a simple example at the end of the video as well.
