🚨 5 Mistakes I Made as a Web Developer (And How I Fixed Them) 💻 When I started my journey as a MERN developer, I made mistakes that cost me hours of debugging, lost sleep, and sometimes even frustration 😅. Over time, I realized these were lessons in disguise. Here’s what I learned: 1️⃣ Not validating inputs properly I used to rely only on frontend validation. Big mistake! Always validate on both frontend and backend. It saves your app from crashes and security issues. 2️⃣ Messy folder/file structure Early projects were chaos. Components, pages, services — everything mixed up. Following a clean folder structure keeps your project scalable and easy to maintain. 3️⃣ Copy-pasting code without understanding it I thought “why reinvent the wheel?” but blindly copying code leads to bugs you can’t debug. Always understand what your code is doing. 4️⃣ Ignoring async/await errors Promises failing without proper try/catch handling caused unexpected crashes. Always handle errors properly and log them. 5️⃣ Not optimizing images or API calls Large images and unoptimized APIs slowed down my apps. Optimizing assets and APIs improves performance drastically. 💡 These mistakes taught me that attention to detail, understanding the fundamentals, and patience are key for any web developer. I’m sharing this hoping it helps beginners avoid the same pitfalls. 🔹 Question for you: Which of these mistakes have you faced in your projects? Or do you have any tips to avoid them?
