本文为读 lodash 源码的第一百零四篇,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 baseUniq from './.internal/baseUniq.js'

《lodash源码分析之baseUniq》

源码分析

uniq 一样, uniqBy 一样,uniqWith同样也是简单地调用 baseUniq 来实现,这次传的是 comparator 参数。

源码如下:

function uniqWith(array, comparator) {
  comparator = typeof comparator === 'function' ? comparator : undefined
  return (array != null && array.length)
    ? baseUniq(array, undefined, comparator)
    : []
}

这里会对 comparator 参数做个检测,如果不为 function 则重置为 undefined
