 While the props and the env are already present on the actual instance of the component and are

-The observed state is actually information about which variables are being observed by the component:
-when any property of a reactive object is being read by the component, the component will subscribe
-to this property which means it will listen to any change that can occur on the property and render
-when such a change occurs. This can be visualized easily within the devtools inside of the observed
-state section: observed properties of the reactive object(s) are displayed in bold while the others
-are greyed out. Do keep in mind that a greyed out property in the observed state of one component
