本文为读 lodash 源码的第三十五篇,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 baseWhile from './.internal/baseWhile.js'

lodash源码分析之baseWhile

源码分析

function dropWhile(array, predicate) {
  return (array != null && array.length)
    ? baseWhile(array, predicate, true)
    : []
}

dropWhiledropRightWhile 一样,内部也是调用 baseWhile 方法,两者唯一不同的是最后一个参数,也即 fromRight 参数,dropWhile 中没有传,也即为假值,表示从左往右遍历,因此两者唯一的区别在于遍历顺序。

dropRightWhile 的分析见: lodash源码分析之dropRightWhile
