Relaxed JSON

Are you frustrated that you cannot add comments into your example JSON structure or easily strip them? Relaxed JSON is a simple solution. Small JavaScript library with only one exposed function RJSON.transform /* string → string */.

Relaxed JSON (modified BSD license) is a strict superset of JSON. Valid JSON will not be changed by RJSON.transform. But in addition there are few extensions helping writing JSON by hand.

• Comments are stripped : // foo and /* bar */ →      . Comments are converted into whitespace, so your formatting is preserved.
• Trailing comma is allowed : [1, 2, 3, ] → [1, 2, 3]. Works also in objects { "foo": "bar", } → { "foo": "bar" }.
• Identifiers are transformed into strings : { foo: bar } → { "foo": "bar" }.
• Single quoted strings are allowed : 'say "Hello"' → "say \"Hello\"".

For the source code, see the GitHub repository.
