+
+A super light (0.5K) and fast circular JSON parser, directly from the creator of [CircularJSON](https://github.com/WebReflection/circular-json/#circularjson).
+
+Usable via [CDN](https://unpkg.com/flatted) or as regular module.
+
+```js
+// ESM
+import {parse, stringify} from 'flatted/esm';
+
+// CJS
+const {parse, stringify} = require('flatted/cjs');
+
+const a = [{}];
+a[0].a = a;
+a.push(a);
+
+stringify(a); // [["1","0"],{"a":"0"}]
+```
+
+### 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'
+```
