- JASON is just like JSON, but unlike JSON it can:
serialize objects with methods
serialize objects with cyclic references
understand Dates, Regexps, Booleans, etc, and restore them with .parse() with their proper types/classes.
understand and serialize all the JS primitives, including undefined
properly recreate the holes in Arrays
JASON lets you pass objects as text between processes and/or threads.
Warning: unlike JSON, JASON is unsafe. You should only use it in contexts where you have strong guarantees that the strings that you pass to the JASON parser have been produced by a JASON formatter from a trusted source.
