👥 Mini-project: from your card to a team

Second checkpoint of your app: you go from modeling ONE person to managing a whole team with arrays of objects and pulling statistics with map, filter and reduce.

What you'll learn

• Model several entities as an array of objects.
• Iterate and transform collections with map to extract data.
• Reduce a collection into a single value with reduce (e.g. an average).
• Compose small functions to generate the report of a mini-app.
