Think back to the last time you looked at an unfamiliar block of code. Did you immediately understand what it was doing? If not, you’re not alone – many software developers, including myself, find it challenging to grasp unfamiliar code quickly…
I would have liked some comments explaining the rules we are trying to enforce or a link to the product requirements for it. Changing the rules requirements is the most likely reason this code will ever be looked at again. The easier you can make it for someone to change them the better. Another reason to need to touch the code is if the user model changes. I suppose we might also want a different password hash or to store the password separately even a different outcome if the validation fails. Or maybe have different ruled for different user types. When building a function like this I think less about “ideals” and more about why someone might need to change what I just did and how can I make it easier for them.
