Available since v1.4.0

description

equalsBy :: (Function | String getter, Any item1, Any item2) => Boolean

Returns true if the values returned by the getter are equals on both items. The getter can be provided as a Function or a String. If getter is a Function, then equalsBy will retrieve the comparison value from both items using the provided function. If it is a String, then equalsBy will use it as a key and retrieve the value associated to this key on both items. equalsBy uses equals internally to compare the two values returned by getter.

examples

providing a key name as a string

import { equalsBy } from 'conductor'

const obj1 = { id: 1, name: 'Anakin' }
const obj2 = { id: 1, name: 'Darth Vader' }

equalsBy('id', obj1, obj2) // true
equalsBy('name', obj1, obj2) // false

using a function as getter

import { equalsBy } from 'conductor'
import { get } from 'conductor'

const obj1 = { id: 1, name: 'Anakin' }
const obj2 = { id: 1, name: 'Darth Vader' }

equalsBy(get('id'), obj1, obj2) // true
equalsBy(get('name'), obj1, obj2) // false
