TypeScript to the rescue! I just prefer strongly typed languages, but it's things like this that disappear (for the most part) when you have types. I personally can't keep types in my head as well as some, so when the language forces me to, it helps a lot. Vanilla JS just makes me feel like I'm walking on egg shells. Then we can get into a lot of fun when we get to type systems like SML and Rust where you start to really touch on some power (but can become intimidating). I'm still a bit weary of trying to hop into Haskell.
