# dequal [](https://github.com/lukeed/dequal/actions)
|
||
|
||
> A tiny (304B to 489B) utility to check for deep equality
|
||
|
||
This module supports comparison of all types, including `Function`, `RegExp`, `Date`, `Set`, `Map`, `TypedArray`s, `DataView`, `null`, `undefined`, and `NaN` values. Complex values (eg, Objects, Arrays, Sets, Maps, etc) are traversed recursively.
|
||
|
||
> **Important:**
|
||
> * key order **within Objects** does not matter
|
||
> * value order **within Arrays** _does_ matter
|
||
> * values **within Sets and Maps** use value equality
|
||
> * keys **within Maps** use value equality
|
||
|
||
|
||
## Install
|
||
|
||
```
|
||
$ npm install --save dequal
|
||
```
|
||
|
||

## Usage
|
||
|
||
```js
|
||
import { dequal } from 'dequal';
|
||
|
||
dequal(1, 1); //=> true
|
||
dequal({}, {}); //=> true
|
||
dequal('foo', 'foo'); //=> true
|
||
dequal([1, 2, 3], [1, 2, 3]); //=> true
|
||
dequal(dequal, dequal); //=> true
|
||
dequal(/foo/, /foo/); //=> true
|
||
dequal(null, null); //=> true
|
||
dequal(NaN, NaN); //=> true
|
||
dequal([], []); //=> true
|
||
dequal(
|
||
[{ a:1 }, [{ b:{ c:[1] } }]],
|
||
[{ a:1 }, [{ b:{ c:[1] } }]]
|
||
); //=> true
|
||
|
||
dequal(1, '1'); //=> false
|
||
dequal(null, undefined); //=> false
|
||
dequal({ a:1, b:[2,3] }, { a:1, b:[2,5] }); //=> false
|
||
dequal(/foo/i, /bar/g); //=> false
|
||
```
|
||
|
||
## API
|
||
|
||
### dequal(foo, bar)
|
||
Returns: `Boolean`
|
||
|
||
Both `foo` and `bar` can be of any type.<br>
|
||
A `Boolean` is returned indicating if the two were deeply equal.
|
||
|
||
|
||
## Benchmarks
|
||
|
||
> Running Node v10.13.0
|
||
|
||
The benchmarks can be found in the [`/bench`](/bench) directory. They are separated into two categories:
|
||
|
||
* `basic` – compares an object comprised of `String`, `Number`, `Date`, `Array`, and `Object` values.
|
||
* `complex` – like `basic`, but adds `RegExp`, `Map`, `Set`, and `Uint8Array` values.
|
||
|
||
> **Note:** Only candidates that pass validation step(s) are listed. <br>For example, `fast-deep-equal/es6` handles `Set` and `Map` values, but uses _referential equality_ while those listed use _value equality_.
