What small coding habits have helped improve your code’s readability?

Implementing 'self-documenting code' is crucial! If you can clearly express intentions through your code structure and naming, it helps both you and others understand it later on. Comments should mainly focus on explaining the reasoning behind complex logic, not reiterating what the code does.

It may sound basic, but commenting is key! When you write a function, describe what it does and anything it relies on in the comments. I've learned this the hard way—after taking a long break from a project, I found my own code confusing because I hadn’t included clear comments. Consistently naming your files meaningfully also goes a long way; don't name them something ridiculous just because you can!

One great habit is to reduce side effects in your code. For example, if you're using switch statements or complex if-else chains, consider encapsulating them within a function that returns a state. This makes it easier to avoid missing branches as you expand your logic. Also, break long conditions into boolean variables with descriptive names, or extract them into separate functions. Structuring your code properly and keeping UI and database logic separate really enhances readability too. Instead of relying heavily on comments (which can become outdated), let the code itself provide clarity, using comments sparingly—only when the logic is complex or when explaining why something is needed rather than what it does.

Reading a style guide for the programming language you're using can really help, especially if you're new. They often contain beginner tips and best practices that can improve your code quite a bit.

Start your files or functions with a comment that explains what they're supposed to do. This way, it’s easier for anyone reading the code to get a sense of its purpose at a glance. And remember, your explanations should be general enough to remain relevant even if the code changes.
