Code Explorer Command Center

You have learned each system separately. Now connect them: create a rescue bot from a class, request mission data from an API, wait with async/await, and keep the command center safe with try/catch.

🧩 The full app pipeline

Real apps are teams of ideas. A class models your rescue bot. An API supplies changing mission data. Asynchronous code waits without freezing the screen. Error handling gives the crew a safe retry when a signal fails.

🏆 Capstone challenges

Create an object

Choose a bot class and build it with new.

Await mission data

Complete one successful asynchronous API request.

Catch a broken signal

Simulate a signal storm and let catch protect the app.

Recover and retry

Turn off the storm and retry the failed request.

Command the whole network

Rescue crews at all three API endpoints.

📚 What you learned

class defines a reusable blueprint and new creates an object.
fetch() asks an API for data from another system.
async/await keeps asynchronous steps readable and in order.
try/catch/finally handles failure, recovery, and cleanup safely.
A complete app connects data, logic, interface updates, and user actions.
