Remove JDOCs and comments. You can create a technical guide page on the wiki section for the block / utils here instead:
https://github.com/adobecom/da-express-milo/wiki

I had started on this path on the previous Repo: https://github.com/adobecom/express-milo/wiki/Picker-(widget)
We can be as specific and as detailed as we wish there. Feel free to document as much as you see fit.

[yeibercano]

Move comments and JSDOC to technical guide on wiki instead.
