JS implementation to compare add-on versions.
npm install addons-moz-compare 
A JavaScript library to compare Mozilla add-on versions that follow the Manifest Version Format.
This library exposes a mozCompare() function that takes two (string) versions A and B and returns:
- -1 if A < B
- 0 if A == B
- 1 if A > B
This implementation matches the Firefox implementation except that there are only 3 different possible return values (Firefox returns strictly negative and strictly positive values instead of -1 and 1).
```
npm i addons-moz-compare
or
``
yarn add addons-moz-compare
``
const { mozCompare } = require('addons-moz-compare');
Use window.mozCompare` after having included the source of this library.
