|
## 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 |
|
|
|
Node.js v9.11.1: |
|
|
|
``` |
|
fast-deep-equal x 226,960 ops/sec ±1.55% (86 runs sampled) |
|
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) |
|
underscore.isEqual x 128,668 ops/sec ±0.75% (91 runs sampled) |
|
lodash.isEqual x 44,895 ops/sec ±0.67% (85 runs sampled) |
|
deep-equal x 51,616 ops/sec ±0.96% (90 runs sampled) |
|
deep-eql x 28,218 ops/sec ±0.42% (85 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 |
|
``` |
|
|
|
To run benchmark (requires node.js 6+): |
