Week 3 · Day 4 — Error Handling & Caching

Theme: API Playmaker 🌐⚽

Coach Intro

Days 1-3 you were making calls in ideal conditions. Perfect connection. API working. Data exactly where you expected it.

Real world? Different story. APIs go down. Connections time out. Rate limits hit. Data fields are missing. Your code needs to handle all of it without crashing.

Today we make everything bulletproof. A program that crashes is a program that doesn't get used.

"A scout who panics when the stadium WiFi cuts out is useless. You need to handle disruptions, fall back to your notes, and keep going. That's what error handling and caching do for your code."
