The 2 Styles Of Bug Searching

When you’re stuck on a tough bug, how you approach it can make a huge difference in how quickly you find the root cause. Here are the core points from the lesson:

• Top-down debugging starts from the full application and removes pieces to isolate the bug, while bottom-up starts with a clean slate and adds code until the bug appears
• Bottom-up debugging can dramatically speed up iteration and discovery in large, complex codebases, even if it requires more upfront effort
• A key mindset is to “move the ball forward” by adding logs, setting alerts, or gathering information that will help your future self debug faster
• Forming clear written updates or questions based on your debugging history allows you to get much higher-quality help from others
