Delete Your Code

Understand the importance of deleting existing code to maintain a clean, organized, and secure codebase, and learn how to build confidence in this process through code reviews, testing, and standardized code commenting.

Key takeaways

Delete existing code makes it harder to understand and maintain the codebase.
Codebase should only contain code that delivers needed functionality, no extra, obsolete code.
Confidence to delete code increases with understanding what the code does, verification of functionality changes, ability to restore changes, and easy tracking of changes.
Code reviews and testing can help identify unused code and assure functionality is not broken.
Naming structure and standardized code commenting can improve code readability and understanding.
Having processes in place for commitment, testing, and code review helps maintain a clean, organized, and secure codebase.
Maturity of the project can influence the approach to code development and the tools used.
Code ownership and responsibility can be a barrier to refactoring and deleting obsolete code.
Having a backup and restore procedure, automated testing, and a code review process can help developers feel more confident in deleting code.
Code delete should be done consistently, and there should be a process for removing obsolete code.
It’s important to understand the process of deleting code and why it’s necessary to make it happen seamlessly.
Tools like ESLint can help identify unused code, and tests can verify functionality changes.
Developer psychology plays a role in code maintenance, and building confidence in deleting code can lead to better code hygiene.
Code comments can help understanding of the code, and automated testing can verify functionality changes.
Removing code can make it harder to track and revert changes, so it’s important to have processes in place.
Having a clear understanding of the code and its purpose can make it easier to delete old code.
Deleting code can make it harder to modify code in the future, but it’s important to keep code tracked and versioned.
It’s important to have a consistent process for removing obsolete code and to build confidence in deleting code.
The codebase should be kept up to date and cleaned regularly to ensure no obsolete code lingers.
