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 )
// [
//     { name: 'Marlin', weight: 105, source: 'ocean' },
//     { name: 'Salmon', weight: 22, source: 'river' }
// ]
