Examples of code refactoring include fixing incorrect formatting, renaming nondescriptive variables, removing duplicate or unused functions and breaking up large, long methods into smaller, more manageable blocks.

What is the difference between refactoring and rewriting code?

Refactoring is about improving the existing code without changing how it works, making it easier to understand and maintain. On the other hand, rewriting means starting fresh with a new codebase, which can be necessary when the old code is too complicated or outdated.

What does refactoring mean?

Refactoring is the process of restructuring code, while not changing its original functionality. The goal of refactoring is to improve internal code by making many small changes without altering the code's external behavior.

Is refactoring good or bad?

The reason you refactor is to make your code easier to work with: so making changes is faster and produces fewer bugs. If you refactor too early, you're not making much of an improvement and wasting time; if you refactor too late, you're stuck in a mess where everything is really hard to do.

What are the problems with refactoring?

The most common cause of refactoring problems is not in the code -- it's a lack of proper tools. Refactoring nearly always includes renaming variables and methods, changing method signatures, and moving things around. Trying to make all these changes by hand can easily lead to disaster.
