Small serialization helper for those who wants to get JS representation of object but gets only this dirty JSON.

Sometimes it's useful to serialize object into the JS user-readable representation but the only option you have is JSON which adds all this damn quotes around any keys (incl. valid identifiers), indents entire contents of any objects/arrays etc.

This small serializer allows you to overcome that and get pretty representations, just as you would write it with own hands in code:

{a: 1}

{
  "a": 1
}

{a: 1}

{a: 1, b: 2}

{
  "a": 1,
  "b": 2
}

{a: 1, b: 2}

{a: 1, b: 2, c: 3}

{
  "a": 1,
  "b": 2,
  "c": 3
}

{
  a: 1,
  b: 2,
  c: 3
}

[{a: 1, b: 2, c: 3, '-': '+'}]

[
  {
    "a": 1,
    "b": 2,
    "c": 3,
    "-": "+"
  }
]

[{
  a: 1,
  b: 2,
  c: 3,
  "-": "+"
}]

[{a: 1}, {b: 2}]

[
  {
    "a": 1
  },
  {
    "b": 2
  }
]

[
  {a: 1},
  {b: 2}
]

You can optionally pass options object as second argument (serialize(obj, { /*...options...*/ })).

Possible options are below:

Type: Number|String Default: ''

Initial indentation of output (generated indentation will be relative to this one). It can be either number of spaces or explicit string.

Type: Number|String Default: 2

Indentation to be used for nested representations. It can be either number of spaces or explicit string (like '\t').

Type: Boolean Default: false

If set to true, generates JSON-compatible output (all the keys are wrapped with quotes, but indentation is still optimized).
