There a certain things to tune from this module. Your task is addressing these points:

- JavaScript have many ways for declaring a function, the module must transform them into standard function syntax.
- If a function it's declared inside a variable, it's treated as a function, not a variable.
- Event listeners cannot be inside the `call` object, since they have their own object.

Complete your task, but prioritize high quality code and respect the current design defined in our module, adapting your changes to follow the same principles and patterns.
