If memory serves, by the way, Brainfuck just maps to C code.
Nope, While brainfuck can be compiled (which can be said about every programming language) it is mostly an interpreted language.
or a language like C++, which compiles directly to machine language, it can take minutes or hours (in the more extreme cases) to test any changes you make to the source code. It's a tradeoff between development time and execution time.
i've never heard anyone include compile time with dev time.
