replaceOrAppend

基础用法

给定一个项目数组、一个项目和一个身份函数，如果数组中已存在该项目，则返回一个新数组，其中该项目在现有项目的索引位置被替换；如果不存在，则将其附加到数组的末尾。

import { replaceOrAppend } from 'radash'

const fish = [
  {
    name: 'Marlin',
    weight: 105
  },
  {
    name: 'Salmon',
    weight: 19
  },
  {
    name: 'Trout',
    weight: 13
  }
]

const salmon = {
  name: 'Salmon',
  weight: 22
}

const sockeye = {
  name: 'Sockeye',
  weight: 8
}

replaceOrAppend(fish, salmon, f => f.name === 'Salmon') // => [marlin, salmon (weight:22), trout]
replaceOrAppend(fish, sockeye, f => f.name === 'Sockeye') // => [marlin, salmon, trout, sockeye]
