诗歌是语言的花朵,任何怒放的花都会随着时间凋零,而花粉的种子也就在空间里随风四散,可能他们就躲在任何不为人知的土地的角落里,静静的等待另一个春天的来临。

本文为读 lodash 源码的第二十六篇,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 isArrayLike from './isArrayLike.js'
import isObjectLike from './isObjectLike.js'

《lodash源码分析之isObjectLike》

源码分析

function isArrayLikeObject(value) {
  return isObjectLike(value) && isArrayLike(value)
}

isArrayLikeObject 其实是 isObjectLikeisArrayLike 的组合,需要检测的值必须要满足 isObjectLikeisArrayLike 的检测。

isArrayLike 函数中,像字符串也会被当作是类数组,但是在 isArrayLikeObject 中,value 的类型的 typeof 返回值必须是 object ,因为 value 要先经过 isObjectLike 检测。
