as is defined as An element type to render as (string or function). in the most of the components in semantic-UI-react. What does that mean?
My understanding is that it somehow changes the component in whatever is as is.
Example:
https://react.semantic-ui.com/modules/sidebar
has Sidebar as={Menu} then the children are <Menu.Item name='...'> without typical <Menu/> that is required to start the menu.
