🚨 Backend Devs, You Know This Struggle 🚨

You build the API.
You test it in Postman.
Everything works flawlessly. ✅
No errors. No surprises. Smooth sailing.

But then…
🚨 The frontend team integrates it, and suddenly—𝗯𝗼𝗼𝗺—nothing works.

You double-check:
🔸 Request body? Correct.
🔸 Headers? Fine.
🔸 Auth token? Looks good.

So what went wrong?

🧠 These are the kinds of bugs that haunt us:
• Postman bypasses browser-level CORS restrictions
• The frontend might structure the JSON 𝘴𝘭𝘪𝘨𝘩𝘵𝘭𝘺 differently
• Content-Type headers could be missing or incorrect
• Or maybe… a sneaky middleware is quietly sabotaging the request

📌 𝗧𝗮𝗸𝗲𝗮𝘄𝗮𝘆:
Just because it works in Postman doesn’t mean it works in the browser.

Welcome to the joys of backend debugging. 😅

🌐 Mastering the Language of the Web – HTTP Status Codes

Whether you're a web developer, backend engineer, or just starting out in tech, understanding HTTP status codes is crucial. These simple 3-digit numbers are how the server and browser communicate—letting us know if things are running smoothly or something has gone wrong.

Here's a quick breakdown:

✅ 200 OK – Everything is working perfectly
🔁 301 & 302 – Redirection in action
🚫 401 & 403 – Access denied
❌ 404 Not Found – The classic broken link
💥 500, 502, 503 – Server-side issues that need attention

Understanding these codes not only helps in debugging but also improves your ability to build better, more reliable web applications.

💡 Pro Tip: Always handle these errors gracefully in your UI for a better user experience!

📊 How Does Big O Work?

Big O notation is a powerful tool used in computer science to evaluate how algorithms scale.

✅ It tells us how the performance of code changes as the input size increases.
✅ There are best, average, and worst-case scenarios for every algorithm.
✅ Big O applies to time, memory, and storage, not just how fast code runs.
✅ It helps choose the right algorithm or data structure for the job.
✅ It shows the growth rate, not the actual speed. So testing with real data is still essential.

💡 Have you ever optimized a piece of code just by understanding its time complexity?
