Unit test our JS functions

[ChristofLee]

This is overkill but good practice.

I would achieve this using Jest.

You would then need to implement browserify to enable module.export and require.

Unit testing is a good idea. Let's put this in future works. Once the JS code is separated and minified, we can add tests as well.

I can do this if you (@PrabhanshuAttri) approve the method I mentioned above?

Assign this to me and I will make a PR for this issue.

Go ahead. Make sure you create a separate PR for this.
