Why does my programming code keep getting debugged repeatedly, and what can I do to prevent it?

I completely understand your frustration - it can be really demotivating to keep debugging the same issues over and over. I've been there too, and I think I can help you identify the root cause and suggest some ways to prevent it.

One possible reason is that your codebase is getting too complex, and it's hard to keep track of all the different changes. This is where refactoring comes in - breaking down your code into smaller, more manageable pieces, and making sure each piece has a single responsibility. For example, if you have a function that's doing too many things, try breaking it down into smaller functions, each with its own responsibility. This will make it easier to debug and maintain your code.

Another reason could be that you're not catching errors and warnings early enough. To help with this, you can use tools like ESLint or JSHint to scan your code for potential issues before you even run it. You can also use a code editor with built-in debugging tools, like Chrome DevTools or Visual Studio Code, to catch errors as you write your code.

As for coding best practices, I'd recommend following the Single Responsibility Principle (SRP) - each piece of code should have only one reason to change. This will make your code more modular and easier to maintain. You can also use design patterns like the Model-View-Controller (MVC) pattern to separate your code into different layers, making it easier to debug and maintain. Finally, make sure you're regularly reviewing and testing your code to catch issues before they become major problems.
