useState function is used to keep track of data that changes.

When that data changes, React will detect that and call the function that cause that.

Creating is a React Element and if this React Element (Component) contains more React elements, it will continue to do so until there are no more.

Each React element ( a JS function ) when it's executed is return an object describing the new UI desired state A.K.A. a snapshot.

If these snapshot are different, React will spot the differences and commit those changes into the DOM if there are any differences.
