Description

A small typo can destroy build. Please add a simple test that will validate the correctness of the event.js file.

How would you like to achieve that? I'd suggest some Github Action running test on pull request. Do you have any other idea?

Exactly, let's prepare regular Jest test case which just loads and parse data and then let's run it using Github Actions 👍
