How React Works?
React is a JavaScript library that uses declarative programming to construct efficient user interfaces. Using React, we can create single-page applications and mobile apps. React uses virtual DOM, which is a JavaScript version of a DOM tree. As a result, it will use the virtual representation of the DOM when reading or writing to it. The virtual DOM will then attempt to update the browser's DOM in the most efficient manner possible.

It's can not be pass any component any where. if user interfare website, they can be change anything in website interface it is called state. If user inteface in the ui state can be change but props could not be change.
