https://dev.to/lenmorld/quick-rest-api-with-node-and-express-in-5-minutes-336j (my 5 stars to this author)

Also, other useful links while practicing these exercises:

All in all, to overcome the CORS issue while playing around with express & rest api:

npm install cors

In server.js...
let cors = require('cors')
server.use(cors())

This would set the Access-Control-Allow-Origin: *
