+
+A super light (0.5K) and fast circular JSON parser, directly from the creator of [CircularJSON](https://github.com/WebReflection/circular-json/#circularjson).
+
+Now available also for **[PHP](./php/flatted.php)**.
+
+```js
+npm i flatted
+```
+
+Usable via [CDN](https://unpkg.com/flatted) or as regular module.
+
+```js
+// ESM
+import {parse, stringify} from 'flatted';
+
+// CJS
+const {parse, stringify} = require('flatted');
+
+const a = [{}];
+a[0].a = a;
+a.push(a);
+
+stringify(a); // [["1","0"],{"a":"0"}]
+```
+
+## Flatted VS JSON
+
+As it is for every other specialized format capable of serializing and deserializing circular data, you should never `JSON.parse(Flatted.stringify(data))`, and you should never `Flatted.parse(JSON.stringify(data))`.
+
+The only way this could work is to `Flatted.parse(Flatted.stringify(data))`, as it is also for _CircularJSON_ or any other, otherwise there's no granted data integrity.
+
+Also please note this project serializes and deserializes only data compatible with JSON, so that sockets, or anything else with internal classes different from those allowed by JSON standard, won't be serialized and unserialized as expected.
+
+
+### New in V1: Exact same JSON API
+
+  * Added a [reviver](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#Syntax) parameter to `.parse(string, reviver)` and revive your own objects.
+  * Added a [replacer](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify#Syntax) and a `space` parameter to `.stringify(object, replacer, space)` for feature parity with JSON signature.
+
+
+### Compatibility
+All ECMAScript engines compatible with `Map`, `Set`, `Object.keys`, and `Array.prototype.reduce` will work, even if polyfilled.
+
+
+### How does it work ?
+While stringifying, all Objects, including Arrays, and strings, are flattened out and replaced as unique index. `*`
+
+Once parsed, all indexes will be replaced through the flattened collection.
+
+<sup><sub>`*` represented as string to avoid conflicts with numbers</sub></sup>
+
+```js
+// logic example
+var a = [{one: 1}, {two: '2'}];
+a[0].a = a;
+// a is the main object, will be at index '0'
+// {one: 1} is the second object, index '1'
+// {two: '2'} the third, in '2', and it has a string
+// which will be found at index '3'
+
+Flatted.stringify(a);
+// [["1","2"],{"one":1,"a":"0"},{"two":"3"},"2"]
+// a[one,two]    {one: 1, a}    {two: '2'}  '2'
+```

+# Flatted Specifications
+
+This document describes operations performed to produce, or parse, the flatted output.
+
+## stringify(any) => flattedString
+
+The output is always an `Array` that contains at index `0` the given value.
+
+If the value is an `Array` or an `Object`, per each property value passed through the callback, return the value as is if it's not an `Array`, an `Object`, or a `string`.
+
+In case it's an `Array`, an `Object`, or a `string`, return the index as `string`, associated through a `Map`.
+
+Giving the following example:
+
+```js
+flatted.stringify('a');                     // ["a"]
+flatted.stringify(['a']);                   // [["1"],"a"]
+flatted.stringify(['a', 1, 'b']);           // [["1",1,"2"],"a","b"]
+```
+
+There is an `input` containing `[array, "a", "b"]`, where the `array` has indexes `"1"` and `"2"` as strings, indexes that point respectively at `"a"` and `"b"` within the input `[array, "a", "b"]`.
+
+The exact same happens for objects.
+
+```js
+flatted.stringify('a');                     // ["a"]
+flatted.stringify({a: 'a'});                // [{"a":"1"},"a"]
+flatted.stringify({a: 'a', n: 1, b: 'b'});  // [{"a":"1","n":1,"b":"2"},"a","b"]
+```
+
+Every object, string, or array, encountered during serialization will be stored once as stringified index.
+
+```js
+// per each property/value of the object/array
+if (any == null || !/object|string/.test(typeof any))
+  return any;
+if (!map.has(any)) {
+  const index = String(arr.length);
+  arr.push(any);
+  map.set(any, index);
+}
+return map.get(any);
+```
+
+This, performed before going through all properties, grants unique indexes per reference.
+
+The stringified indexes ensure there won't be conflicts with regularly stored numbers.
+
+## parse(flattedString) => any
+
+Everything that is a `string` is wrapped as `new String`, but strings in the array, from index `1` on, is kept as regular `string`.
+
+```js
+const input = JSON.parse('[{"a":"1"},"b"]', Strings).map(strings);
+// convert strings primitives into String instances
+function Strings(key, value) {
+  return typeof value === 'string' ? new String(value) : value;
+}
+// converts String instances into strings primitives
+function strings(value) {
+  return value instanceof String ? String(value) : value;
+}
+```
+
+The `input` array will have a regular `string` at index `1`, but its object at index `0` will have an `instanceof String` as `.a` property.
+
+That is the key to place back values from the rest of the array, so that per each property of the object at index `0`, if the value is an `instanceof` String, something not serializable via JSON, it means it can be used to retrieve the position of its value from the `input` array.
+
+If such `value` is an object and it hasn't been parsed yet, add it as parsed and go through all its properties/values.
+
+```js
+// outside any loop ...
+const parsed = new Set;
+
+// ... per each property/value ...
+if (value instanceof Primitive) {
+  const tmp = input[parseInt(value)];
+  if (typeof tmp === 'object' && !parsed.has(tmp)) {
+    parsed.add(tmp);
+    output[key] = tmp;
+    if (typeof tmp === 'object' && tmp != null) {
+      // perform this same logic per
+      // each nested property/value ...
+    }
+  } else {
+    output[key] = tmp;
+  }
+} else
+  output[key] = tmp;
+```
+
+As summary, the whole logic is based on polluting the de-serialization with a kind of variable that is unexpected, hence secure to use as directive to retrieve an index with a value.
+
+The usage of a `Map` and a `Set` to flag known references/strings as visited/stored makes **flatted** a rock solid, fast, and compact, solution.
