    This implies that Javascript will get moving in the correct direction once it finishes installing dependencies, but it's just going to get fucked with incorrect behavior that doesn't even have the courtesy to throw an actual error.

    incorrect behavior that doesn’t even have the courtesy to throw an actual error.

    To be fair, this can be said of C. A C executable only really forces a crash out when you royally screw up beyond the bounds of your memory. Otherwise functions just return a negative value and calling code that never bothers to check just keep on going.

    Golang is similar, slightly mitigated that if you are assigning any return value from a function, you must also explicitly receive an error and you know full well that you are being lazy if you don't handle it. Well unless you use a panic/recover scheme but golang community will skewer you alive for casually suggesting that and certainly third party libraries aren't going to do it that way.

      only true if your language compiles to c. fortran peeps are safe.

      I thought it compiles to LLVM intermediate representation and then to the machine code of the requested platform arch. Am I missing something?

        only if you design it using llvm. llvm is pretty new.

              Technically any language runtime can end in a segmentation fault.

              For some languages, in principle this shouldn't be possible, but the runtimes can have bugs and/or you are calling libraries that do some native code at some point.

              Even safe rust can do it, if we allow compiler bugs

                    I have seen a Java program I wrote terminate with SIGSEGV. I think a library was causing it.

                    Yup, can confirm. We had a wrapper to a C++ library using JNI, so whenever this library crashed so did the entire JVM.

                        I guess they fixed the weirdness involving calling main later in the program

                            Duke, Java's mascot. A triangular shaped character with a red nose.

                              Or, rather, most compiled languages are just syntactic sugar on top of assembly, and that's especially true with C. (Oh, you can use curly brances and stuff for blocks? That's sure easier to read than the label mess you get with assembly.)

                              Assembly is a little too high level for me. I prefer to directly write machine code.

                                  Fortran is from 1957, LLVM is from 2003. It's probably like C where there is a compiler tool chain that goes through LLVM like you describe and others that go directly to executables.

                                    It's not what you can use that language to do - all general purpose languages are Turing Complete, so what you can do with them is exactly equal. It is about what the language will do for you. Rust compiler will stop you from writing memory unsafe code, C compiler cannot do that.

                                    Fun fact, some languages are not turing complete and I believe people would still consider them programming languages. They're typically targeted at making mathematical proofs.

                                        C++ is home sick, currently the doctor (compiler) is not sure whether it's got the flu or a terminal cancer.

                                          There are dozens of us! Millions of devices and dozens of us know about Duke!

                                          Fun fact, Duke is released to the public. I forget in what way exactly, but Oracle freed them (him? it?).
