Additional context

I think this formatter could be a good thing to keep package.json files formatted correctly in all projects or everytime someone edit them manually. I use it daily to keep them clean when "Pretty Diff" is formatting them a little bit different.

I think @Glavin001 commented some day that I should keep the line break in the arrays, this would fix this problem, because Pretty Diff always keep them on one line.

{
  "dependencies": {},
  "version": "1.0.0",
  "keywords": ["thing"],
  "name": "foo",
}

after

{
  "name": "foo",
  "version": "1.0.0",
  "keywords": ["thing"],
  "dependencies": {}
}
