本文为读 lodash 源码的第三百五十九篇,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 map from './map.js'
《lodash源码分析之map》
over 接收一组函数 iteratees ,并返回一个函数,当函数被调用时,会遍历迭代器,并将函数的参数作为迭代器的参数传入,得到一组结果返回。
over
iteratees
源码如下:
function over(iteratees) { return function(...args) { return map(iteratees, (iteratee) => iteratee.apply(this, args)) } }
其实就是调用 map 来遍历迭代器,将每个迭代器的结果返回。并且调用器在调用时,this 绑定到函数创建时的 this 。
map
this
