#editdistance

> A much faster than the naïve Levenshtein distance algoritme.

> This is an modified version of the Berghel Roach Levenshtein algortime
> with the time complexity of `O(n + d^2)` (n longest string, d edit distance).
> This is much faster compared to the naïve approach there uses `O(n*m)` (n and m are string lengths)
CPU time.

## Installation

```sheel
npm install editdistance

## Documentation
