Code refactoring is the process of taking an existing piece of code and restructuring it to improve its readability, flexibility, and maintainability. It can be done by any developer or team member without having to involve a programmer who specializes in design patterns.
The best way to think about code refactoring is as a kind of house cleaning–you’re just reorganizing your code so that it’s easier for you to find things when you want them (and future developers will thank you too).
Benefits of code factoring
- Easier to read and understand – The general structure of the code is more clear.
- Easier to debug – Refactoring makes it much easier for developers to track down bugs because they can follow the logic through a series of transformations, instead of trying to figure out what someone else was thinking when writing the original code.
- Reduced risk of future errors – When refactoring code, developers are more likely to fix problems in the original logic than add new bugs.
- Reduced need for future redesigns – Refactoring can be done without having to start from scratch or invest a lot of time and energy into reworking existing code.
- Improved collaboration with other developers – It’s easier to work collaboratively with other developers when everyone is on the same page and using common vocabulary.
What does code refactoring involve?
- Searching for problematic areas of your code (often the ones you’re trying to fix).
- Finding common patterns among those problems that can be fixed with a single change, like changing an if statement to a while statement.
- Grouping similar changes together and making them apply to multiple parts of your code.
- Changing the order of blocks in your code, so that statements are executed one after another rather than all at once. This can help prevent errors from cascading through large chunks of code when an error is made elsewhere.
Drawbacks of code refactoring
- Time is needed for the developer to complete a thorough review of their changes.
- The process can be time consuming and may not fix all problems in one go; it’s important to keep working at things until they’re done right!
What are some common misconceptions about code refactoring?
Many developers believe that refactoring is a waste of time because the changes are so minor. However, this is not true! Refactoring can make your code easier to understand and use without having to change any functionality whatsoever.
A lot of developers also think that they should only do small updates in one sitting–but you don’t have to worry about how long it takes or how many times you need to work on something before it’s done right; just keep working at things until they’re done right!
It’s important for teams who write software together (like those building an app) to talk with each other openly about when their own individual processes will be finished, as well as what needs attention next. This way everyone knows where the team is at, and what can be tackled next.
