Spent 2 hours on this, ran out of time
shortcuts / time limitations: -> didn't implement db or filtering yet. -> testing not set up -> tests in package json hardcoded to 1 file instead of all directories -> Didn't use env for API key, just hardcoded -> Didn't use TypeScript -> Paid little attention to tidying directories etc.
npm i
cd src
node app.js
Set up your API key in K.js
Use this data in postman to test

"lastName": "My last name",
