debonx / react-container-component.js

Created January 4, 2020 11:17

React: Container components from presentational components.

	/* Separating container components from presentational components is a popular React programming pattern.
	Here’s the basic idea behind it: if a component has to have state, make calculations based on props, or manage any other complex logic, then that component shouldn’t also have to render HTML-like JSX.
	Instead of rendering HTML-like JSX, the component should render another component. It should be that component’s job to render HTML-like JSX.
	Following this pattern separates your business logic from your presentational logic. */
