One tree, every notation
Everything below is this library compiled to JavaScript — the same code
the tests run, in the browser. The document is read as the dialect you
pick, so a trailing comma and a // comment are refused by
JSON with the line and the column, and accepted by JSON5 — and the
sentence you see is Refused::message, printed by the
library, not written by this page.
Written every way
Pick a notation to see the document that way. The text is the core writer; the hex is the format's encoder, byte for byte.
Lay it out your way
The formatter takes an indent in spaces, or one tab a level, sorts the names, and escapes everything above U+007E as ASCII. It is the library's formatter, not a copy of it.
