I have an object like this:

var object = {
  a: 5,
  b: ["a", "b"],
  c: {
    a: 1,
    b: 2
  }
}

And I would like to be transformed to a flat one like this:

var output = {
  a: 5,
  b: "a, b",
  "c.a": 1,
  "c.b": 2
}

Is there any function already done about this?

I have a mongodb database that has hierarchy documents and I need them to be converted to a flat one. Thanks

(The answer is that you need to do this work on the client). – WiredPrairie Jul 31 '13 at 07:24
yes, I know, but I'm asking how.. – Totty.js Jul 31 '13 at 09:19
What problem are you having? As I'm sure you know this isn't a site for coding requests. – WiredPrairie Jul 31 '13 at 18:48
I'm asking if there is already a library that is doing that instead of reinventing it.. – Totty.js Jul 31 '13 at 21:28
Tool/library questions on StackOverflow are also generally closed. – WiredPrairie Aug 01 '13 at 00:06
Your request seems really simple to write in whatever programming language you're using, and a bit unique. I'd suggest just writing it your self. – WiredPrairie Aug 01 '13 at 00:07
