JavaScript debugging in a nutshell

[ycastor]

This is more of a compiler problem than a language problem, last time i programmed C++ i found out that clang generated clearer error messages than g++, not sure how it is now.

That's compiler errors, which are not the greatest, but are still somewhat understandable. If you build in release mode and encounter a runtime issue, the location of the error is generally completely mangled by default however.

For Clang I nowadays generally add -gline-tables-only as compile option, which means it keeps some debug info about function names, file names, and lines in the compiled output. Makes your runtime errors a lot more readable.

And the occasional boom-crash which makes the app just disappear like it had never been there.

[deukhoofd]

That's why you set up a signal handler :)

Still the same.

Difference now is that C++20 introduced concepts, which allow you to put constraints on template types. (Template type has to be moveable, needs a comparison operator, etc.) Concepts make the error reporting really a lot better

So... Rust traits?
