Lab 7: Game Logic for Duolingo

Welcome to your Dev Shop Challenge.

Today, you are not completing a coding exercise —
you are solving a client problem using logic.

🧑🏽‍💼 Client Brief

Client: Duolingo

Problem: Duolingo wants to improve beginner engagement by making progress feel more meaningful.

Points exist — but the experience doesn’t react to them.

---

🎯 Your Goal

Build a prototype that:

• Tracks learner progress (XP, streaks, points, etc.)
• Responds differently based on performance
• Uses randomness to keep things engaging
• Provides feedback that changes over time

---

✅ Technical Requirements

Your prototype must include:

• One main progress variable
• One if / else if / else chain
• At least two comparison operators
• One array used for randomness

---

🧠 Think Like a Developer

Ask yourselves:

• What does success look like for Duolingo?
• When should a user feel rewarded?
• How many learner states exist?
• What logic controls those moments?

Remember:

Client goals → product behavior → JavaScript logic

---

🌱 Stretch Ideas (Optional)

• Add emojis or visual changes
• Add a reset button
• Introduce streak bonuses
• Change feedback wording to match Duolingo’s tone

🔁 Connection to charity: water

The same logic you build here powers:

• Game mechanics
• Progress tracking
• Win / lose states

You’ll reuse this thinking in your charity: water game project — just with a different mission.

You’re not just writing JavaScript.

You’re teaching an app how to think.
