# simple-maybe
Simple helper functions (`map`, `filter`, `flatMap`, `getOrElse`, etc.) for transforming `T | undefined` types (`Maybe`).
## Example
``` ts
import { mapMaybe, Maybe, safeHead } from './index';
const maybeHead = safeHead([1,2,3])
const mappedMaybe = mapMaybe(maybeHead, x => x + 1) // Maybe<2>
console.log(mappedMaybe) // 2
```
## TODO
- [ ] Provide curried forms for better composition
