- [](https://coveralls.io/github/epoberezkin/fast-deep-equal?branch=master)
-
-
- ## 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
- ```
