10 Common Coding Mistakes That Every Developer Should Avoid.

Balraj Singh on January 13, 2025

We all make mistakes. If you're a developer, you’ve probably spent hours (okay, maybe days) debugging something that could’ve been easily avoided. ...

Yes, I agree that if you don't follow these rules, you won't be able to write good code. But to follow them all, you'll have to spend time )

Great list! These mistakes hit close to home—I’ve definitely been guilty of hardcoding values and skipping tests in the past. It’s a good reminder that small habits like proper version control and refactoring regularly can make a huge difference. Thanks for sharing these tips

Its not developers that we have to convince these things of, its our executives. Most software is written to support a product that is integrated into hardware or supports a product that is not Software. These folks seem to think that writing code is making it work and then shipping it! End of story...move on. We ship the equivalent of bread boarded circuits in code everyday and are
shocked SHOCKED about the high cost of the software life cycle after "release".

Not thinking twice before hitting the keyboard.

I tell other developers to comment and document like there is a problem at 1am after a long day with the cto over your shoulder when you'll need it. Documentation is for you not other people.
