I watched closely at this tutorial -> https://www.youtube.com/watch?v=w7ejDZ8SWv8&t=4978s (React Crash Course 2021 (Task Tracker App)) <-
I am going to build on this app and experiment with it. I hope that one day it will be a working keep-track fitness app.
npm install
Run React dev server (http://localhost:3000)
npm start
Run the JSON server (http://localhost:5000)
npm run server
npm run build
