Lisa SpiroWhat is JSON, anyway? Well, by a happy coincidence, it turns out that the syntax JavaScript uses for defining data objects is rather broadly compatible with other languages. This makes it a sort of lowest-common-denominator syntax for specifying data. Other folks have covered this better than I can, so I'll just send you straight to the source: json.org.
One of the key benefits of JSON is that because it is essentially JavaScript syntax, browsers can "parse" JSON data simply by calling the JavaScript eval function. This is both easy and fast because it takes advantage of native code in the browsers to do the parsing. (This is also why JSON can be a security problem; if the JSON string actually contains non-JSON code, then calling eval on it is quite dangerous.) -
