Koelle Sort

Also known as alphanum sort

alphanum sort is designed to produce more sensible results than ascii sort for certain use cases

| z10.doc | z2.doc |
| z100.doc | z3.doc |

- Sorts alphanumeric strings
- Sorts numbers
- Sorts letters
- Sorts a number of different date formats
- Sorts decimal numbers
- Sorts zero padded numbers

- Sorts empty strings
- Sorts by number first

$3

- Does not support numbers separated by multiple decimal points (e.g. IP Address, Semver formatting)

Usage

``
npm install @cablanchard/koelle-sort
`

`javascript
const { alphanum } = require("@cablanchard/koelle-sort");

const sorted = [
"file10.txt",
"file1.txt",
"file2.txt",
].sort(alphanum);

/**
* [
* "file1.txt",
* "file2.txt",
* "file10.txt",
