Arrow functions don't work sometimes as event handlers
I find that when I write the event handler as an arrow function, whenever I'm using $(this) it doesn't work, but when I write a regular function the $(this) works.

You've discovered one of the main differences between conventional and arrow functions: the binding of "this" was intentionally omitted. There are a few others, for full details see this MDN page on Arrow Functions.
Arrow functions are not intended as a universal replacement for conventional functions. In particular, the documentation says:
Arrow function expressions are ill suited as methods, and they cannot be used as constructors.
Oh I see. Arrow functions are not scoped as regular functions.
