# lodash源码分析之pullAll | ||
|
||
本文为读 lodash 源码的第六十一篇,后续文章会更新到这个仓库中,欢迎 star:[pocket-lodash](https://github.com/yeyuqiudeng/pocket-lodash) | ||
|
||
gitbook也会同步仓库的更新,gitbook地址:[pocket-lodash](https://www.gitbook.com/book/yeyuqiudeng/pocket-lodash/details) | ||
|
||
## 依赖 | ||
|
||
```javascript | ||
import basePullAll from './.internal/basePullAll.js' | ||
``` | ||
|
||
[《lodash源码分析之basePullAll》](internal/basePullAll.md) | ||
|
||
## 源码分析 | ||
|
||
```javascript | ||
function pullAll(array, values) { | ||
return (array != null && array.length && values != null && values.length) | ||
? basePullAll(array, values) | ||
: array | ||
} | ||
``` | ||
|
||
有了 `basePullAll` ,要实现 `pullAll` 就简单了。 | ||
|
||
其实 `pullAll` 最终调用的是 `basePullAll` ,只不过在调用之前,对 `array` 和 `values` 做了一些基本的检测。 | ||
|
||
```javascript | ||
array != null && array.length | ||
``` | ||
|
||
确保 `array` 有传,并且不为空 | ||
|
||
```javascript | ||
values != null && values.length | ||
``` | ||
|
||
确保 `values` 有传,并且不为空 | ||
|
||
如果条件不满足,则直接返回 `array` ,否则调用 `basePullAll` 。 | ||
