TIL that C# and Java have a goto statement.
In C# at least,
goto
can take you between case labels in a switch statement (rather than using fallthrough), which I don't view as being nearly as bad. For example, you can dogoto case 1
orgoto default
to jump to another case.The only other use of
goto
I find remotely tolerable is when paired with a labelled loop statement (like putting a label right before afor
loop), but honestly Rust handles that far better with labelled loops (and labelled block expressions).I've programmed C# for nearly 15 years, and have used
goto
twice . Once to simplify an early break from a nested loop, essentially a nestedcontinue
. The second was to refactor a giant switch statement in a parser, essentially removing convolutedwhile
loops, and just did agoto
the start.It's one of those things that almost should never be used, but the times it's been needed, it removed a lot of silliness.
