Migrate Codebase from JavaScript to TypeScript

[erikyo]

This pull request aims to migrate the existing codebase from JavaScript to TypeScript. The transition to TypeScript will enhance the code quality, provide better type safety, and improve overall development experience.

Benefits:

• Improved Type Safety: TypeScript's static type checking will help catch errors at compile-time, reducing runtime errors.
• Enhanced Developer Experience: IDEs can provide better autocomplete, navigation, and refactoring tools with TypeScript.
• Scalability: TypeScript makes it easier to maintain and scale the codebase, especially in larger projects.
• Better Documentation: Type annotations serve as a form of documentation, making the code more understandable, with a cleaner code.
