## Install
|
|
|
|
```bash
|
|
npm install fast-deep-equal
|
|
```
|
|
|
|
|
|
## Features
|
|
|
|
- ES5 compatible
|
|
- works in node.js (0.10+) and browsers (IE9+)
|
|
- checks equality of Date and RegExp objects by value.
|
|
|
|
|
|
## Usage
|
|
|
|
```javascript
|
|
var equal = require('fast-deep-equal');
|
|
console.log(equal({foo: 'bar'}, {foo: 'bar'})); // true
|
|
```
|
|
|
|
|
|
## Performance benchmark

|
|
nano-equal x 218,210 ops/sec ±0.79% (89 runs sampled)
|
|
shallow-equal-fuzzy x 206,762 ops/sec ±0.84% (88 runs sampled)

|
|
assert.deepStrictEqual x 1,777 ops/sec ±1.05% (86 runs sampled)
|
|
ramda.equals x 13,466 ops/sec ±0.82% (86 runs sampled)
|
|
The fastest is fast-deep-equal
|
|
```
