How do _you_ define legacy code? I can think of several potential definitions.

How do you define legacy code?
|
|
|
|
|
|
|
|
|
|
Is it code written by previous Developers who worked on the codebase?
|
|
|
|
|
|
|
|
|
|
Is it code you wrote last week or last month?
|
|
|
|
|
|
|
|
|
|
Is it code for features everyone no longer uses?
|
|
|
|
|
|
|
|
|
|
Is it the "old" part of the application that no one wants to work on?
|
|
|
|
|
|
|
|
|
|
It is any code that's not nice to work on or difficult to change?
|
|
|
|
|
|
|
|
|
|
Is it code written with different conventions to your current ones or in a different style?
|
|
|
|
|
|
|
|
|
|
Is it any code that doesn't have automated tests or wasn't written with test-driven development?
|
|
|
|
|
|
|
|
|
|
Is it code built with outdated tooling or frameworks (like CSS libraries) that were popular then but have since been replaced by something newer?
|
|

## Here's the thing

|
These are just some of the potential definitions I can think of.
|
|
|

|
The term "legacy code" and others, such as "technical debt", often mean different things.
