本文为读 lodash 源码的第一百一十一篇,后续文章会更新到这个仓库中,欢迎 star:pocket-lodash

gitbook也会同步仓库的更新,gitbook地址:pocket-lodash

依赖

import baseXor from './.internal/baseXor.js'
import isArrayLikeObject from './isArrayLikeObject.js'

《lodash源码分析之baseXor》
《lodash源码分析之isArrayLikeObject》

源码分析

xor 调用的是 baseXor ,但是传入的不是数组集,而是不定参数,每个参数都应该为数组或类数组,如果不是数组会被过滤掉。

源码如下:

function xor(...arrays) {
  return baseXor(arrays.filter(isArrayLikeObject))
}

首先使用 ... 操作符将参数收集在 arrays 中。

然后调用数组的 filter 方法,将非数组或类数组的项过滤掉,再调用 baseXor 得出结果。
