## qcompare

the fastest function for comparing two js objects compatible with es6

*according to the author, this comparison script is the fastest in the industry(watch benchmarks)

### Install

npm install --save qcompare

### Usage

const qcompare = require( 'qcompare');

`; // true; // false`

### Features

- support for all new classes ES6;
- very quickly compares;
- correctly compares:
- does not support circular objects;
- object-keys for the Map are compared by reference;

### Benchmarks

For more balanced testing of performance, tests of other projects were used
