本文为读 lodash 源码的第三十篇,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
import baseDifference from './.internal/baseDifference.js' import baseFlatten from './.internal/baseFlatten.js' import isArrayLikeObject from './isArrayLikeObject.js' import last from './last.js'
lodash源码分析之数组的差集
lodash源码分析之baseFlatten
lodash源码分析之isArrayLikeObject
lodash源码分析之last
differenceWith 和 difference 以及 differenceBy 的功能差不多,我们从上一篇文章《lodash源码分析之differenceBy》中已经知道,differenceBy 可以指定迭代器,那 differenceWith 又有什么不同呢?
differenceWith
difference
differenceBy
differenceWith 与 difference 不同的地方在于,differenceWith 可以自定义比较函数。如果不指定比较函数,则 differenceWith 的功能和 difference 完全相同。
differenceWith 和 differenceBy 的源码基本一致,如下:
function differenceWith(array, ...values) { let comparator = last(values) if (isArrayLikeObject(comparator)) { comparator = undefined } return isArrayLikeObject(array) ? baseDifference(array, baseFlatten(values, 1, isArrayLikeObject, true), undefined, comparator) : [] }
可以看到,comparator 是直接传给 baseDifference 的,comparator 便是自定义的比较函数,具体的分析见《lodash源码分析之数组的差集》
comparator
baseDifference
