I love the ternary operator as much as anyone. But dang if it doesn't get hard to read when there is are a few, nested even.
Does that operator compile to faster assembly that if I make the same logic with verbose `if` logic? Is that a language specific outcome?
- gnubison 4mo agocond1 ? res1 : cond2 ? res2 : cond3 ? res3 : or_else_res If they are truly nested, then that is confusing. But if you have an if-else chain, then it can be quite readable.
- shevy-java 4mo agoI find that so much harder to read compared to if/else or case/when in ruby. The ? is basically an attempt to use fewer if/else, at the cost of condensed if-else like structure. I always need to look at both parts after the ? whereas in a single if or elsif I don't. case/when in ruby is even better here e. g. regex check: def foo(i) case i when /^cat/ handle_cats when /^dog/ handle_dogs (I ommitted the "end"s here to just focus on the conditional logic.)

- matheusmoreira 4mo agoAn elegant weapon, for a more civilized age...
- froh 4mo agoor if cond1 then res1 else if cond2 then res2 else if cond3 then res3 else or_else_res or if cond1 then res1 elif cond2 then res2 elif cond3 then res3 else or_else_res what is most lua-like?
