Responsive Job Listing in Typescript OOP approach

What are you most proud of, and what would you do differently next time?

This is an OOP aproach using templates and classes. I would add an abstract class to serve as a listener with its 3 main methods from which the job and the filter state would inherit from.

This is a react like approach with components and listeners written in pure typescript.

What specific areas of your project would you like help with?

I would highly appreciate any comments with my choice to go for an OOP based approach.
