Would the code have worked if we didn't put e as a parameter in the beginning, and proceeded to write input.target?

That's right, the event object (often represented by the parameter name "e") give you access to a number of things, including the target element.

You don't need to include it as a parameter is you don't use it anywhere in your handler. But personally, I like to pass it anyway to acknowledge that the system always supplies it, and to simplify things if code added later needs it.
