Keep empty arrays & objects on same line

[movingobjects]

I'd love to have (an option for?) empty arrays/objects be outputted on the same line.

For example, given the data:

const data = { a: [], b: {} };

Running stringify(data, { space: 2 }) returns:

{
  "a": [
  ],
  "b": {
  }
}

Whereas JSON.stringify(data, null, 2) returns:

{
  "a": [],
  "b": {}
}

I find the latter, with the empty arrays/objects on the same line, much easier to read.

It also seems to matches how most other JSON tools handle empty arrays/objects (e.g., VSCode's Format Document command, https://jsonformatter.org/, https://www.jsonformatter.io/, and others).

Thanks!

That seems reasonable, and I agree it's easier to read. A new boolean option, say, collapseEmpty, should cover it.
