Complex values (eg, Objects, Arrays, Sets, Maps, etc) are traversed recursively.6 7> **Important:**8> * key order **within Objects** does not matter9> * value order **within Arrays** _does_ matter10> * values **within Sets and Maps** use value equality11> * keys **within Maps** use value equality12 13 14## Install15 16```17$ npm install --save dequal18```19 20## Modes21 22There are two "versions" of `dequal` available:23 24#### `dequal`25> **Size (gzip):** 489 bytes<br>26> **Availability:** [CommonJS](https://unpkg.com/dequal/dist/index.js), [ES Module](https://unpkg.com/dequal/dist/index.mjs), [UMD](https://unpkg.com/dequal/dist/index.min.js)27 28#### `dequal/lite`29> **Size (gzip):** 304 bytes<br>30> **Availability:** [CommonJS](https://unpkg.com/dequal/lite/index.js), [ES Module](https://unpkg.com/dequal/lite/index.mjs)31 32| | IE9+ | Number | String | Date | RegExp | Object | Array | Class | Set | Map | ArrayBuffer | [TypedArray](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/TypedArray#TypedArray_objects) | [DataView](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/DataView) |33|-|:-:|:-:|:-:|:-:|:-:|:-:|:-:|:-:|:-:|:-:|:-:|:-:|:-:|34| `dequal` | :x: | :white_check_mark: | :white_check_mark: | :white_check_mark: | :white_check_mark: | :white_check_mark: | :white_check_mark: | :white_check_mark: | :white_check_mark: | :white_check_mark: | :white_check_mark: | :white_check_mark: | :white_check_mark: |35| `dequal/lite` | :+1: | :white_check_mark: | :white_check_mark: | :white_check_mark: | :white_check_mark: | :white_check_mark: | :white_check_mark: | :white_check_mark: | :x: | :x: | :x: | :x: | :x: |36 37> <sup>**Note:** Table scrolls horizontally!</sup>38 39## Usage40 41```js42import { dequal } from 'dequal';43 44dequal(1, 1); //=> true45dequal({}, {}); //=> true46dequal('foo', 'foo'); //=> true47dequal([1, 2, 3], [1, 2, 3]); //=> true48dequal(dequal, dequal); //=> true49dequal(/foo/, /foo/); //=> true50dequal(null, null); //=> true51dequal(NaN, NaN); //=> true52dequal([], []); //=> true53dequal(54 [{ a:1 }, [{ b:{ c:[1] } }]],55 [{ a:1 }, [{ b:{ c:[1] } }]]56); //=> true57 58dequal(1, '1'); //=> false59dequal(null, undefined); //=> false60dequal({ a:1, b:[2,3] }, { a:1, b:[2,5] }); //=> false61dequal(/foo/i, /bar/g); //=> false62```63 64## API65 66### dequal(foo, bar)67Returns: `Boolean`68 69Both `foo` and `bar` can be of any type.<br>70A `Boolean` is returned indicating if the two were deeply equal.71 72 73## Benchmarks74 75> Running Node v10.13.076 77The benchmarks can be found in the [`/bench`](/bench) directory.
