[ React & TS ] Newsletter Sign Up (Feedback is Appreciated)

Hello! This is my solution for this Challenge!

This is my first time using TypeScript and honestly, I'm a little confused with it. However, I didn't plan to stop using TypeScript.

So, if you had any good resources (or courses) about TypeScript, Please share it!. Still, Any Feedback is Appreciated so if you could look at the code and give a feedback, it really helps. Also, if you haven't review other people code or give a feedback before, feel free to use this as a practice.

Anyway, Happy Coding!
