Legacy Code: Reimagining instead of Rewriting

In this chapter, they discuss whether it is worth saving and refactoring legacy code or if it's better to just make some temporary fixes. They explain that in general, rewriting the code is not a good idea, except in certain cases such as building a new product based on the lessons learned from the first one. They also suggest taking a small chunk of the code base to rewrite and ship it as a microservice alongside the legacy code. They emphasize the importance of having safety nets like automated tests and documentation in place before making any significant changes to the code.
