Title *

Published (uncheck if you want to fiddle around before making the page public)

Description (in case you feel further explanation is needed)(Markdown syntax is allowed)

Are you a spammer? (just answer the question)

Preparation code

Preparation code HTML (this will be inserted in the <body> of a valid HTML5 document in standards mode) (useful when testing DOM operations or including libraries)

Include JavaScript libraries as follows: <script src="//cdn.ext/library.js"></script>

Define setup for all tests (variables, functions, arrays or other objects that will be used in the tests) (runs before each clocked test loop, outside of the timed code region) (e.g. define local test variables, reset global variables, clear canvas, etc.) (see FAQ)

var isValid = function(s) {
  // All empty whitespace is not valid.
  if (/^\s*$/.test(s)) {
    return false;
  }

// Don't make these static since they have the global flag.
  var backslashesRe = /\\["\\\/bfnrtu]/g;
  var simpleValuesRe =
      /"[^"\\\n\r\u2028\u2029\x00-\x08\x0a-\x1f]*"|true|false|null|-?\d+(?:\.\d*)?(?:[eE][+\-]?\d+)?/g;
  var openBracketsRe = /(?:^|:|,)(?:[\s\u2028\u2029]*\[)+/g;
  var remainderRe = /^[\],:{}\s\u2028\u2029]*$/;

return remainderRe.test(s.replace(backslashesRe, '@').
      replace(simpleValuesRe, ']').
      replace(openBracketsRe, ''));
};
