unique

​

Basic usage

Given an array of items — and optionally, a function to determine their identity — return a new array without any duplicates.

import { unique } from 'radash'

const fish = [
  {
    name: 'Marlin',
    weight: 105,
    source: 'ocean'
  },
  {
    name: 'Salmon',
    weight: 22,
    source: 'river'
  },
  {
    name: 'Salmon',
    weight: 22,
    source: 'river'
  }
]

unique(fish, f => f.name) // => [marlin, salmon]
