Debugging Like a Pro: Tips Every Developer Should Know (Without Losing Your Sanity!)

Introduction

Let’s be real—debugging is like being a detective in a crime movie where you are both the detective and the criminal. You write code, it breaks, you investigate, and after hours of frustration, you realize it was a missing semicolon. 😩

But fear not! Debugging doesn’t have to be a soul-crushing experience. In this post, we’ll cover practical debugging techniques to make your life easier and—dare I say—fun! (Okay, maybe not fun, but at least less painful.)

1. Rubber Duck Debugging: Yes, Talk to a Toy 🦆

Have you ever explained your code to someone and suddenly realized the mistake yourself? That’s Rubber Duck Debugging—literally explaining your code to a rubber duck (or anything else that listens and doesn’t judge you).

🛠 Try This: Next time you’re stuck, grab a rubber duck (or an imaginary friend) and walk through your code line by line. You’ll be surprised how often you find the bug yourself!

2. Console.log() is Your Best Friend (But Don’t Overuse It) 📟

Logging values to the console is a lifesaver, but let’s be honest—we’ve all done this:

console.log("Here");
console.log("Still here");
console.log("Why is this not working?!");

Instead, use descriptive logs and group them:

console.log("User Data:", user);
console.table(usersArray);
console.time("Loop Execution");
for (let i = 0; i < 10000; i++) {} // Simulating work
console.timeEnd("Loop Execution");

🔹 Pro Tip: Use console.table() for objects/arrays and console.trace() to find where functions were called.

3. The Art of Debugger Statements 🕵️‍♂️

Ever wish you could pause time and inspect your code step by step? Use debugger; inside your functions and open Developer Tools (F12 in most browsers) to pause execution and inspect values like a pro.

function test() {
    let num = 42;
    debugger; // Execution will pause here in DevTools
    num++;
    return num;
}

🔍 Where to Use It: Complex loops, API calls, or anywhere you feel like your code is possessed.

4. Read the Error Message (Yes, Seriously) 🚨

We’ve all ignored error messages at some point, but they actually tell you exactly what went wrong (most of the time). Instead of blindly copying and pasting into Google, take a deep breath and:

✅ Read the file name and line number
✅ Identify the error type (e.g., TypeError, ReferenceError)
✅ Check the stack trace for clues

---

5. When in Doubt, Google it (But Smartly) 🕵️‍♀️

Google is a developer’s second brain, but knowing how to search makes all the difference:

❌ "My code is broken please help JavaScript"
✅ "TypeError: Cannot read property ‘length’ of undefined JavaScript"
✅ "React useEffect not updating state on API call"

🔹 Pro Tip: Use MDN and Stack Overflow for accurate answers.

6. Take a Break (Seriously, Walk Away) ☕

Sometimes, the best debugging tool is distance. If you’ve been staring at a problem for hours with no solution, do this:

1. Step away from the screen (yes, physically move!)
2. Grab a coffee, take a walk, or do some push-ups 💪
3. Come back with fresh eyes and—boom!—you’ll often see the mistake instantly.

---

7. Write Self-Explaining Code (Your Future Self Will Thank You) ✍️

Debugging is way easier when your code is readable. Instead of writing something like this:

let x = y.z * 2 / foo(5);

Write:

let itemPrice = product.price;
let discount = applyDiscount(5);
let finalPrice = (itemPrice * 2) / discount;

💡 Rule of Thumb: If you have to explain what a variable does, rename it.

---

Conclusion

Debugging doesn’t have to be an endless nightmare. With the right mindset and techniques, you can track down bugs faster and keep your sanity intact. So next time your code isn’t working, remember:

✅ Explain it to a rubber duck
✅ Log smartly (not excessively)
✅ Use debugger; wisely
✅ Actually read the error message
✅ Take breaks when needed
