Writing code is an art, but writing readable code? That’s a skill.
You might think that as long as your program runs and gets the job done, you’re good to go. But let’s be honest — badly written code is a nightmare, not just for others but for your future self. Have you ever opened a file you wrote six months ago and thought, “What was I even doing here?” Yeah, we’ve all been there.
Readable code isn’t just a nice-to-have; it’s a necessity. Whether you’re working in a team or going solo, clean and clear code makes debugging, updating, and collaboration a breeze. Plus, it saves time and mental energy. So how do you write code that others (and you) can understand effortlessly? Let’s break it down.
Start with meaningful names. Variable names like x, y, or temp might feel convenient in the moment, but they’re utterly confusing down the road. Imagine coming across a function that takes parameters x and y. What do they mean? Instead, go for descriptive names like userAge or isLoggedIn. Sure, it takes a few extra seconds to type, but it saves hours of head-scratching later.
