js-object-compare v1.0.0

A package that offers functions to help with object comparison (same keys, same key/values, same content, in A but not in B). Includes tests to show it works.

Installation

$ npm install js-object-compare

Usage

const jsoc = require("js-object-compare");

const obj1 = { num: 1, block1: { num: 2 } };
const obj2 = { block1: { num: 2 }, num: 1 };
const obj3 = { num: 1, block1: {} };
const obj4 = { num: 1, char: "a", block1: { num: 3 } };

// returns true because both objects have the exact same key/value pairs (it does not matter they are not in the same order).
console.log(jsoc.sameContent(obj1, obj2));
// returns an object with block1 stripped away, because the object, at that location, does not contain anything.
console.log(jsoc.clearEmpties(obj3));
// returns all key/value pairs that are the same in both objects.
console.log(jsoc.equalKeyValue(obj1, obj4));
// returns all keys that exist in both objects (values may be different because of that they are undefined in the resulting object).
console.log(jsoc.equalKey(obj1, obj4));
// returns all key/value pairs that are part of param1 but do not exist in param2 (values may be different).
console.log(jsoc.in_A_ButNotIn_B(obj4, obj1));
