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.
replyDoes that operator compile to faster assembly that if I make the same logic with verbose `if` logic? Is that a language specific outcome?
cond1 ? res1 :
cond2 ? res2 :
cond3 ? res3 :
or_else_res
Or they could just ask granddaddy for advice:
reply (cond (cond1 res1)
(cond2 res2)
(cond3 res3)
(t else_res))
An elegant weapon, for a more civilized age...
replyor
reply if cond1 then res1
else if cond2 then res2
else if cond3 then res3
else or_else_res
if cond1 then res1
elif cond2 then res2
elif cond3 then res3
else or_else_res
I find that so much harder to read compared to if/else or case/when in ruby.
replyThe ? 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
Unless you mess up its associativity, like PHP until 7.4.
