| |
| |
| ## 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+): |
| |
| ```bash |
| npm install |
| node benchmark |
| ``` |
