JS Identical

A simple library to check that JS/JSON value is identical each other (Typescript support). The implementation will ignore the order of array or key index.

This module is a sub implementation of the js-deep-equals. Arrays are compared by creating a Merkle Tree out of the input and comparing the top level hashes. hashing is done using murmur v3.

Usage

Installation

npm i js-identical
