What is Deep-Eql?

Deep Eql is a module which you can use to determine if two objects are "deeply" equal - that is, rather than having referential equality (a === b), this module checks an object's keys recursively, until it finds primitives to check for referential equality. For more on equality in JavaScript, read the comparison operators article on mdn.

As an example, take the following:

11 === 1 // These are primitives, they hold the same reference - they are strictly equal
21 == '1' // These are two different primitives, through type coercion they hold the same value - they are loosely equal
3{ a: 1 } !== { a: 1 } // These are two different objects, they hold different references and so are not strictly equal - even though they hold the same values inside
4{ a: 1 } != { a: 1 } // They have the same type, meaning loose equality performs the same check as strict equality - they are still not equal.
5
6import deepEql from "deep-eql";
7deepEql({ a: 1 }, { a: 1 }) === true // deepEql can determine that they share the same keys and those keys share the same values, therefore they are deeply equal!

Installation

Node.js

deep-eql is available on npm.

$ npm install deep-eql

Usage

The primary export of deep-eql is function that can be given two objects to compare. It will always return a boolean which can be used to determine if two objects are deeply equal.

Rules

Strict equality for non-traversable nodes according to Object.is:
- eql(NaN, NaN).should.be.true;
- eql(-0, +0).should.be.false;
All own and inherited enumerable properties are considered:
- eql(Object.create({ foo: { a: 1 } }), Object.create({ foo: { a: 1 } })).should.be.true;
- eql(Object.create({ foo: { a: 1 } }), Object.create({ foo: { a: 2 } })).should.be.false;
When comparing Error objects, only name, message, and code properties are considered, regardless of enumerability:
- eql(Error('foo'), Error('foo')).should.be.true;
- eql(Error('foo'), Error('bar')).should.be.false;
- eql(Error('foo'), TypeError('foo')).should.be.false;
- eql(Object.assign(Error('foo'), { code: 42 }), Object.assign(Error('foo'), { code: 42 })).should.be.true;
- eql(Object.assign(Error('foo'), { code: 42 }), Object.assign(Error('foo'), { code: 13 })).should.be.false;
- eql(Object.assign(Error('foo'), { otherProp: 42 }), Object.assign(Error('foo'), { otherProp: 13 })).should.be.true;
Arguments are not Arrays:
- eql([], arguments).should.be.false;
- eql([], Array.prototype.slice.call(arguments)).should.be.true;
