You're touching on a really interesting point that I think both C++ and JavaScript have in common. Their specifications are very general-purpose (eg: ECMAScript, ISOC++) and generally decorated with a specific runtimes and standard libraries provided by another party (eg: browser, nodejs, host OS, bare metal, etc.) and often a few different build systems (eg: webpack, gulp, makefiles, CMake, MSVC, etc.). There's also a lot of oppurtunities to "just include" libraries like Boost or an npm dependency. I feel like Rust (eg: `cargo build`) or Ruby gems provide a very different, standardized experienced compared to the two.
