Hmm. Reading this article and reflecting on the times I have encountered the map pattern I initially did not like it. It separates the logic into two different places. That makes it harder to trace through the code and find the right place to modify. You are however right that I have to do it less often using this pattern.
As an electrical engineer, coding is only a small part of what I do. The rest of my day is spent in planning, documentation, testing for regulatory compliance and debugging. Then again, I write firmware for medical equipment. It must be correct or people die.
Imperative style with lots of ifs takes a lot more unit tests to prove it works compared to declarative style. One shouldn’t be debugging, one should be testing and isolating complexity out of the main program. This thread is scary, frankly.
Don’t worry about cyclomatic complexity, just do a lot of debugging to make sure people don’t die? Hrm ...
If it has to work or people die, then you really should scrutinize every if statement carefully and see if you can get rid of it. Many ifs are bugs waiting to be discovered.
For further actions, you may consider blocking this person and/or reporting abuse
We're a place where coders share, stay up-to-date and grow their careers.
