Recently, I came across a gem that I would like to share. It’s a book titled “๐—ช๐—ผ๐—ฟ๐—ธ๐—ถ๐—ป๐—ด ๐—˜๐—ณ๐—ณ๐—ฒ๐—ฐ๐˜๐—ถ๐˜ƒ๐—ฒ๐—น๐˜† ๐˜„๐—ถ๐˜๐—ต ๐—Ÿ๐—ฒ๐—ด๐—ฎ๐—ฐ๐˜† ๐—–๐—ผ๐—ฑ๐—ฒ” by Michael Feathers. If you are a software engineer, you will inevitably deal with legacy code such as ancient codebases, code developed by someone else, or even code written by yourself weeks ago that you’ve forgotten about it.

Regardless of whether you are a new software engineer or a seasoned developer, “๐—ช๐—ผ๐—ฟ๐—ธ๐—ถ๐—ป๐—ด ๐—˜๐—ณ๐—ณ๐—ฒ๐—ฐ๐˜๐—ถ๐˜ƒ๐—ฒ๐—น๐˜† ๐˜„๐—ถ๐˜๐—ต ๐—Ÿ๐—ฒ๐—ด๐—ฎ๐—ฐ๐˜† ๐—–๐—ผ๐—ฑ๐—ฒ” is an excellent resource for anyone tackling legacy codebases.
