## Websites and Guides for learning how to optimise your code.

So we know writing code is one thing, but keeping it clean, organised, and easy to maintain? Well that's where the real challenge lies.

So enter refactoring to save our code (and our souls?! 🤔).

## What is Refactoring?

If you're a coder, you've likely heard the term "refactoring" thrown around.

But what does it actually mean? In simple terms, refactoring involves restructuring and optimising existing code without altering its external functionality.

It's all about improving the internal structure, readability, and maintainability of your codebase.

## Why Refactor?

While constantly refactoring might not be at the top of your priorities, it's an essential practice that shouldn't be overlooked.

By regularly refactoring your code, you'll make it easier to understand and modify, reducing [technical debt](https://dev.to/evergrowingdev/the-invisible-threat-to-your-projects-success-and-how-to-deal-with-it-44pa) and minimising the chances of introducing bugs further down the line.

Think of it as a bit of spring cleaning for your applications.

## Learning how to Refactor

Of course, getting into refactoring can seem scary, especially if you're new to the concept.

That's where these five top free resources come in handy, they'll give you the foundational knowledge and techniques needed to refactor [like a pro](https://dev.to/evergrowingdev/how-to-learn-programming-from-the-pros-3k2p).
