I used to call such a code constructions
pyramids.They are so stable like on the picture above.
The true term is actually called guard clause : medium.com/@scadge/if-statements-d...
And as we don't nest conditions, it is not a pyramid, it is flat ;)
That's true. I’m familiar with the term ”guard clause”. It’s a part of defending coding style :) To be clear, I have nothing against guard clauses, I use them very often, sometimes I extract them to separate class to split validation logic into a separate piece of code. To keep the code clean, we can't nest if statements. As you said ”flat” construction is not bad, but the pyramid is, in my opinion, the pure evil.
Agree at 100%
This is my coding style too.
It isn't more code. Same amount of lines actually. And way more readable. :)
Hah! Good catch. Did not even notice. Maybe because of the added return statements.
Great article! Sometimes making compact code isn't the best strategy.
Thank you!
My opinion is that less code = less headaches later on with some exceptions like this one. Of course, don't need to make it as compact as possible until everything is crammed inside one line. Where you can, cut quite a few lines of code.
