sort_by

The order in which an object’s keys are written.

Synopsis

my $json = JSON::PP->new->sort_by(sub { $JSON::PP::b cmp $JSON::PP::a });

What you get back

The object. A code reference, or the name of a sub in JSON::PP, sorts the keys, comparing $JSON::PP::a with $JSON::PP::b; any other true value sorts them as canonical does.
