1 | # Map-Set.prototype.toJSON
2 |
3 | An [ECMAScript](https://github.com/tc39/ecma262) proposal. ~~Currently at **Stage 0**.~~
4 |
5 | This proposal was brought before the committee in the March 2016 meeting, and thoroughly rejected. [Details](https://github.com/DavidBruant/Map-Set.prototype.toJSON/issues/16)
6 |
7 | ## Problem
8 |
9 | Here is the current situation:
10 |
11 | ````js
12 | var s = new Set(['yo', 'ya', true, 8]);
13 |
14 | console.log(JSON.stringify(s)); // '{}'
15 | ````
16 |
17 | This result is unhelpful. Same goes for Map.
18 |
19 |
20 | ## Proposal
21 |
22 | This proposal is about providing a sensible default to the common operation of JSON serialization via default `toJSON` implementations on `Set.prototype` and `Map.prototype`. Of course, userland code can always shadow this value on specific instances.
23 |
24 | ### Map.prototype.toJSON
25 |
26 | The essence of the proposal is captured in this snippet (spec in [markdown](spec.md#mapprototypetojson--) or [HTML](http://davidbruant.github.io/Map-Set.prototype.toJSON/#Map.prototype.toJSON)):
27 |
28 | ````js
29 | Map.prototype.toJSON = function toJSON() {
30 | return [...Map.prototype.entries.call(this)];
31 | }
32 | ````
33 |
34 | ### Set.prototype.toJSON
35 |
36 | The essence of the proposal is captured in this snippet (spec in [markdown](spec.md#setprototypetojson--) or [HTML](http://davidbruant.github.io/Map-Set.prototype.toJSON/#Set.prototype.toJSON)):
37 |
38 | ````js
39 | Set.prototype.toJSON = function toJSON() {
40 | return [...Set.prototype.values.call(this)];
41 | }
42 | ````
43 |
44 | ## Discussion
45 |
46 | There might be a web compat concern if code using native Map and Set or polyfill relies on the current JSON.stringify behavior.

56 | Map.prototype.toJSON / Set.prototype.toJSON
57 |
58 | 1 Map.prototype.toJSON ( )# This function provides an Array representation of an iterable object for use by JSON.stringify .
60 |
61 |
62 | When the
63 | toJSON method is called, the following steps are taken:
64 |
65 |
66 | Let M be the
67 | this value.
68 | Let iterator be ?
69 | GetIterator M )
70 | Let A be !
71 | ArrayCreate 0 ).
73 | Let k be
74 | 0 .
75 | Repeat
76 |
77 | Let Pk be !
78 | ToString k ).
79 | Let next be ?
80 | IteratorStep iterator ).
81 | If next is
82 | false , then
83 |
84 | Perform ?
85 | Set A , "length", k ,
86 | true ).
87 | Return A .
88 |
89 |
90 | Let nextValue be ?
91 | IteratorValue next ).
92 | Let defineStatus be
93 | CreateDataPropertyOrThrow A , Pk , nextValue ).
94 | If defineStatus is an
95 | abrupt completion IteratorClose iterator , defineStatus ).
97 | Increase k by 1.
98 |
99 |
100 |
101 |
102 |
103 | Note The
104 | length property of the
105 | toJSON method is
106 | 0 .
108 |
109 |
110 | 2 Set.prototype.toJSON ( )# The initial value of the
112 | toJSON property is the same function object as the initial value of the
113 | Map.prototype.toJSON property.

11 |
12 | Map.prototype.toJSON ( )
13 | This function provides an Array representation of an iterable object for use by JSON.stringify .
14 |
When the *toJSON* method is called, the following steps are taken:
15 |
16 | 1. Let _M_ be the *this* value.
17 | 1. Let _iterator_ be ? GetIterator(_M_)
18 | 1. Let _A_ be ! ArrayCreate(*0*).
19 | 1. Let _k_ be *0*.
20 | 1. Repeat
21 | 1. Let _Pk_ be ! ToString(_k_).
22 | 1. Let _next_ be ? IteratorStep(_iterator_).
23 | 1. If _next_ is *false*, then
24 | 1. Perform ? Set(_A_, "length", _k_, *true*).
25 | 1. Return _A_.
26 | 1. Let _nextValue_ be ? IteratorValue(_next_).
27 | 1. Let _defineStatus_ be CreateDataPropertyOrThrow(_A_, _Pk_, _nextValue_).
28 | 1. If _defineStatus_ is an abrupt completion, return IteratorClose(_iterator_, _defineStatus_).
29 | 1. Increase _k_ by 1.
30 |
31 | The *length* property of the *toJSON* method is *0*.
32 |
33 |
34 |
35 | Set.prototype.toJSON ( )
36 | The initial value of the *toJSON* property is the same function object as the initial value of the *Map.prototype.toJSON* property.
