just-compare

Part of a library of zero-dependency npm modules that do just do one thing.
Guilt-free utilities for every occasion.

import compare from 'just-compare';

// functions: value1.toString == value2.toString
// arrays: if length, sequence and values of properties are identical
// objects: if length, names and values of properties are identical
