Just a few online JavaScript compression sites. Not obfuscation, just compression --although some of the following do both.


I personally prefer JSON to XML.

  • A JSON validator like JSLint.
  • "JSON for the masses"
  • "JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language."
