That depends if the person who must do the porting knows Make or not and which GNU Make (it's always about GNU Make!) feature had been used. And chances are JS devs don't at all or just as little as the one who wrote the article.

Don't get me wrong: I don't like Make, but I hate CMake and Autotools (and many other C++ build systems) too (and C and C++ and Fortran compilers and their vendors).
