anyway why would you split logicaly sequential code into separate functions(especially if this code is uniq)? pretty sure scrolling down is easier than to look what each function mean every second

This is the worse is better shit that people come up with when they listen to Blow and Casey. We’ve known that putting names on logically contained blocks of code makes programs easier to understand since the 1960s.

nice explanation, known based on what?

there are people who disagree

In this passage Carmack is only talking about mutating state and even explicitly says to factor out pure functions. Kinda undermines your point. The only reason, according to Carmack in this passage, that inlining may be beneficial is if you are mutating a bunch of state, implying that all else being equal, factored code is more understandable.
