Inspired by https://github.com/epoberezkin/fast-deep-equal, re-publish cause it's not support ESM.
## Usage
* use within ESM.
```javascript
import isEqual from '@guanghechen/fast-deep-equal'
console.log(isEqual({foo: 'bar'}, {foo: 'bar'})); // true
```
* use within CommonJS.
```javascript
const isEqual = require('@guanghechen/fast-deep-equal')
console.log(isEqual({foo: 'bar'}, {foo: 'bar'})); // true
```
