Convert project to TypeScript

[dislocated-su]

Suggestion

I've recently been interested in TypeScript as a strong statically typed alternative (typing works like in C#, C++, Java, etc.) to weak dynamically javascript. I prefer strong static typing since it is more verbose and easier to understand, along with providing features like documentation in IDE and autocompletion (IntelliSense).

Converting the project to TS should involve adding the compiler as a dependency and setting up compile-on-save. Additionally, vscode has extensions that add more typescript integration.
