In TS you really can't (that's my point and why I prefer to avoid the language) because of JS and API baggage. But just about every other static language that I've worked in can complain for this kind of thing.

Why does the compiler care about what I know? The compiler itself knows what the function's parameters are and it can tell me that something seems wrong because I'm asking it to call a function that maxes out at 2 parameters with 3 parameters.
TS does catch this kind of thing in a lot of places. It just intentionally decides not to do it for these kinds of callbacks because of the same JS and API baggage.

Hows your compiler supposed to know you don't know what the parameters are?
