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.

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.

Happy coding!
