And in ternary operator

ruby-talk
1

hi,

i would like to do something like the following

if true
do_a
else
d_a
d_b
end

Can this be done using ternary operator?

This seem to give different result:
ifTrue ? do_a : do_a and do_b

Thank you.

'and' is very low precendence operator, and also will only do_b if the
result of do_a is true.

ifTrue ? do_a : (do_a, do_b)

You need a semicolon instead of a comma.
