# scanDirEachSync(path, worker = () => {}, raw = false)
> 串行扫描文件夹，扫描的同时支持更新、过滤操作，一定程度复用遍历。
## 使用
- `path` 待扫描的路径，**必需提供**，{String}
- `worker` 处理器，如果扫描的同时需要更新、过滤操作可提供，一定程度复用穷举，**必需提供**，{ Function }
- 返回 {Object | Boolean}
- `false` 过滤掉当前扫描结果
- `true` 保留当前扫描结果
- 对象字面量，保留 / 更新当前扫描结果
- 其它类型则默认为没有任何处理
- `raw` 是否专门返回未加工的扫描结果，默认 `false`，**可选**，{ Boolean }
- 返回，扫描结果 { Array }
- 如果设置了 `raw` 为 `true`，则返回 **二维数组**，第一项为加工后的扫描结果，第二项为未加工的扫描结果
- 默认返回 **一维数组**，即：加工后的扫描结果
```js
import { log } from "console";
import scanDirEachSync from "@iyowei/scan-dir-each-sync";
log(
scanDirEachSync(
process.cwd(),
(cur, index) => {
return index % 2 === 0 ? cur : false;
},
true
)
);

- [**`scanDirSync()`**][scandirsync]，`worker` 选填，有 `worker`，行为同 `scanDirEachSync()` 一致，否则与 `lsDirSync()` 一致，如果项目中同时使用了 `scanDirEachSync()`、`lsDirSync()`，则推荐使用 `scanDirSync()`；
- [**`scanDir()`**][scandir]，`worker` 选填，有 `worker`，行为同 `scanDirEach()` 一致，否则与 `lsDir()` 一致，如果项目中同时使用了 `scanDirEach()`、`lsDir()`，则推荐使用 `scanDir()`；
- [**`scanDirEach()`**][scandireach]，可在扫描的同时更新或过滤数据，**并行** 实现；
