## Get started

`npm i @pencroff/ts-algorithms --save`

The package doesn't provide any common exports. All required imports should be per item.
For example:

```
import { genericComparator } from '@pencroff/ts-algorithms/dist/primitive/comparator'

const res = genericComparator('A', 'B'); // returns -1, check primitives for details
```
