Add Event and minimal EventTarget

MasatoDev commented 7 months ago

Overview

Thank you for your confirmation. I implemented Event and EventTarget that are related to https://github.com/wasmerio/winterjs/issues/9 without detailed dispatching logic.

Description

This PR is regarded to bellow spec.

https://dom.spec.whatwg.org/#event https://dom.spec.whatwg.org/#eventtarget

I referred to the following code.

https://github.com/denoland/deno/blob/main/ext/web/02_event.js

Scope

Event class
EventTarget class

out-of-scop items

dispatching-events
Case of eventTarget is a Window object or the type is touchstart, touchmove, and so on.

Outstanding issue

Currently, I need import, but I think Event and EventTarget is Global Scope, so which file should I add and implement?
Implementation for window and DOM element events is omitted. Please let me know if there is a problem.
I think there is a discussion about whether to include primordials, but I didn't mention it.

Hey @MasatoDev, thank you for your contribution!

Currently, it is impossible to define global objects in JS/TS. However, I think it would be beneficial to add that in, so I'll create an issue for it and move this to the global scope once that's implemented.
