Use simple and obvious naming
npm now seems to require all-lowercase package names. I find this mostly terrible but I must follow the herd, thus filenames should use kebab-case even though the variable name for that in JavaScript must be camelCase because - i...
How do I use Assert.Throws to assert the type of the exception?
...l fail. However if an exception of the correct type is thrown then you can now assert on the actual exception that you've saved in the variable.
By using this pattern you can assert on other things than the exception message, e.g. in the case of ArgumentException and derivatives, you can assert tha...
Why is it bad practice to call System.gc()?
...n; any that rely on it for performance are most likely broken.
You don't know what sort of garbage collector you are running under. There are certainly some that do not "stop the world" as you assert, but some JVMs aren't that smart or for various reasons (perhaps they are on a phone?) don't do it...

...};
X::a();
return 0;
}
However, I'd question the praxis. Everyone knows (well, now that you do, anyway :)) C++ doesn't support local functions, so they are used to not having them. They are not used, however, to that kludge. I would spend quite a while on this code to make sure it's really o...
Missing return statement in a non-void method compiles
...id method is missing a return statement and the code still compiles.
I know that the statements after the while loop are unreachable (dead code) and would never be executed. But why doesn't the compiler even warn about returning something? Or why would a language allow us to have a non-void met...
