Junior JS developer task

This repository contains an express server.

Use npm start command to start it - server will listen for requests on port 3000.

There is already one GET endpoint on http://localhost:3000 which returns Hello, World! text.

Your task is to add three new endpoints.

When you are done, you can either send a pull request to this repository with your solution or email your solution to HR manager.

You will then receive a detailed review of your code.

Good luck!
