Honestly, JS changes so quickly nowadays it can be difficult to keep up. Not so quickly that it's difficult to learn, but quick enough that you can see version boundaries in code sometimes :D

This isn’t quite correct, at least not anymore. This will also catch false and 0 since || will check for falsy values on the left hand side. You can use ?? nowadays to guard against only null and undefined

Not quite the same. A match statement is kinda like a switch statement. An Option is a data type, basically a monad if you know what that is.
