Presentational and Container Components Pattern in React
In a nutshell, presentational components are concerned with how things look while container components are more concerned with how things work. Container components are components that specify the data a presentational component should render and these components can be reused across different parts of an application.
The pattern is based on the need to separate actual business logic from the UI details by concealing the props we don't care about. It implements that by having a purely presentational component which does not know much about our domain. For example, if the component is a <LikeButton onLike={...} />, it doesn't care what's being liked. It's just a UI element which calls the callback from the onLike prop (that essentially acts as a bridge between the low-level world of UI events, and the world of high-level domain concepts). The role of the container component, then, is to give domain meaning to that presentational component. Following on the example, if we wanted to have a like button for the currently open post, a container component <PostLikeButton /> would be able to figure out what post is currently open and render a <LikeButton onLike={...} /> with the appropriate callback.
