Re: what is benefit of unless ?

in reply to what is benefit of unless ?
in thread unless statements

You can use "else" with "unless".

"unless" means "if not", so it reverses the meaning of an "if" comparison.

See perlsyn for details.

`unless ($boolean) { ... }` [download] is nearly completely equivalent to: `if (not $boolean) { ... }` [download] (The slight difference is in the "last expression evaluated" return value for a subroutine, but that's only a minor distracting point.) -- Randal L.
