JSON (JavaScript Object Notation) is a simple data format. See to the
http://www.json.org/ manpage and 'RFC4627'(the
http://www.ietf.org/rfc/rfc4627.txt manpage).

This module converts Perl data structures to JSON and vice versa using
either the JSON::XS manpage or the JSON::PP manpage.

JSON::XS is the fastest and most proper JSON module on CPAN which must be
compiled and installed in your environment. JSON::PP is a pure-Perl module
which is bundled in this distribution and has a strong compatibility to
JSON::XS.

This module try to use JSON::XS by default and fail to it, use JSON::PP
instead. So its features completely depend on JSON::XS or JSON::PP.

See to the BACKEND MODULE DECISION manpage.

To distinguish the module name 'JSON' and the format type JSON, the former
is quoted by C<> (its results vary with your using media), and the latter
is left just as it is.

Module name : 'JSON'

Format type : JSON
