Posting here to get feedback.

I can't find real differences with react, that would make me want to switch from one to the other

I have a background with socket.io. Should I learn how to use vanilla web sockets or should I use µWebSockets until Why you should never use µWebSockets arrives ? Performance is not a priority right now, and premature optimization can hurt.

I think yarn also has downsides compared to npm. In npm if a dependency updates version patch, the potential security patch is now included in future npm installs. In Yarn you must manually update everything from what I understand

not that dynamic, since cannot respond to specific user actions, unless you can predict what said user is going to ask.

Initially yes, but the second time we can load the html from local disk with the service worker

To an extend but not only. To get rid of the server we need to remove its authority too, which mean the client pseudo server are not just executing , they're doing it without a server telling them.

Why use a custom element link , if it does nothing more than the <a> tag ?

I am also exploring different ways to create "classes" of objects. 

1 way I came up with is to use plain function that just returns a plain Object without prototype, without common functionality.

Methods are instead stored as plain functions as properties of the factory function(in JavaScript a function is also an object), with an explicit 1st argument taking the instance.

It plays well with higher order functions (forEach, Map, Some)
