Is “IF” expensive?
...l. If you're writing high-level code, you don't need to worry about these details at all. You should only care about this if you're writing extremely performance-critical code in C or assembly. If that is the case, writing branch-free code can often be superior to code that branches, even if seve...

The source of the confusion is that in most languages, if you have an interface type that defines a set of methods, the class that implements it "repeat...
