本文为读 lodash 源码的第一百九十三篇,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 getSymbols from './getSymbols.js'
import keys from '../keys.js'

《lodash源码分析之getSymbols》
《lodash源码分析之keys》

源码分析

getAllKeys 的作用跟 keys 的作用差不多,但是 keys 不会获取对象 object 上的 Symbol 类型的属性,getAllKeys 会将 Symbol 类型的属性都返回 。

源码如下:

function getAllKeys(object) {
  const result = keys(object)
  if (!Array.isArray(object)) {
    result.push(...getSymbols(object))
  }
  return result
}

首先调用 keys 得到所有非 Symbol 类型的属性,然后判断如果为非数组类型,则调用 getSymbols 获取所有的 Symbol 类型的属性。
