本文为读 lodash 源码的第三百六十三篇,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 baseProperty from './.internal/baseProperty.js'
import basePropertyDeep from './.internal/basePropertyDeep.js'
import isKey from './.internal/isKey.js'
import toKey from './.internal/toKey.js'

《lodash源码分析之toKey》

源码分析

property 函数接收属性路径 path ,并创建一个函数返回,这个函数接收一个 object ,调用时,会从 object 上取出属性路径 path 的值。

function property(path) {
  return isKey(path) ? baseProperty(toKey(path)) : basePropertyDeep(path)
}

如果传入的 path 本身就是属性名,则调用 baseProperty 来生成函数,否则,调用 basePropertyDeep 来生成函数。

baseProperty 生成的函数性能会更加好。
