XML vs. JSON
Also called JavaScript Object Notation, is a text-
based open standard designed for human-
readable data interchange. It is derived from the
JavaScript scripting language for representing
simple data structures and associative
arrays, called objects. Despite its relationship to
JavaScript, it is language-independent, with
parsers available for many languages.
