qcompare
the fastest function for comparing two js objects compatible with es6
Install
npm install --save qcompare
Usage
const qcompare = require( 'qcompare');
qcompare( { foo: 1 }, { foo: 1 } ); // true
qcompare( { bar: 1 }, { bar: 2 } ); // 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;
