How to Write Efficient Code? - Smashers Hub

What makes some codes efficient while others are not? We often hear that we need to write efficient code, but how do we actually do it? In this article, we will look at how to write code efficiently and how to write structured code, with the ultimate goal of making our code more manageable and easier to maintain. Let’s begin!

Create Your Own Functions!

By using your own functions, you’ll be able to write structured code. When you first start programming, a lot of focus goes into learning syntax, keywords, and libraries. However, learning how to structure your code is one of the most valuable skills that you can learn when you’re just starting out. Organizing your code in a way that makes sense for you will help ensure that it's readable and easy to understand as well as ensuring that it executes quickly. One way to do so is by creating your own functions whenever possible; when creating a function from scratch, think about how exactly it will work before writing any code.

Minimize use of If-Else

Many inexperienced programmers tend to write code that is overly complicated. The use of if-else statements in place of switch statements (where applicable) can simplify your code and make it more efficient. Instead of using a complex set of nested if-else statements, you can simply use a switch statement, which makes it easier for other developers who may be working on your project or looking through your code.

Use Break Loops when Needed!

In certain situations, writing a for loop makes more sense than using a while or do-while loop. A common example is when you need to execute code a specific number of times, in which case a for loop will be more efficient since it only needs one counter variable (though there are instances where counting up can be done much faster with a while loop). More often than not, though, we write loops because we don't know how many times our code will run. In these cases, it's important that your code is written in such a way that it can handle any possible number of iterations. Writing structured code essentially means organizing your code in such a way that if you add another section or two, it doesn't cause other sections of your code to break.

Conclusion

The basics of structured code can take a lifetime to master, but there are ways you can make sure your code is well organized and efficient. To make sure your code is clean and error-free, strive for consistency throughout each of your programming languages. And don’t be afraid to ask for help if you get stuck on a problem. Knowing where to look for answers is just as important as understanding how to write them yourself. Remember: It’s OK not to know everything; it’s perfectly fine not knowing how you’re going to do something in advance. The idea is that you never stop learning or trying new things—just keep at it and eventually, it will all come together!
