Why values on my React form do not update?

Might seem like a bug, it's a feature instead. The explanation goes down to... javascript! As simple as that! We're so used to javascript frameworks doing all sort of things that we forget that displaying the value of a javascript variable in the DOM has to be explicitly done, it's not a default js behaviour. When you want to push the performance and optimize your code, it makes sense to avoid doing it all the time if it's not necessary and that's what most of the js form libraries are doing: preventing unnecessary rerenders. They also all provide a simple and straightforward API to subscribe and react on changes for you to be used consciously.
