Usage

const { deepEqual } = require('@marcm/deep-equal')
// or
import { deepEqual } from '@marcm/deep-equal'
// or if being used for React
import { deepEqual } from '@marcm/deep-equal/react'

// Typed Arrays
deepEqual(new Float32Array([3, 4, 6]), new Float32Array([3, 4, 6])) // true
deepEqual(new Float32Array([3, 4, 6]), new Float32Array([3, 4])) // false
// Objects and array
deepEqual([{ a: 'a' }, { b: 'b' }], [{ a: 'a' }, { b: 'b' }]) // true
// Dates
deepEqual(new Date('2017-06-16T21:36:48.362Z'), new Date('2016-06-16T21:36:48.362Z')) // false
deepEqual(new Date('2017-06-16T21:36:48.362Z'), new Date('2017-06-16T21:36:48.362Z')) // true
