hoc, pure component and react.memo are all ways to optimize React components.
Higher Order Components (HOC) are functions that take a component and return a new component with additional functionality.
Pure Components are components that only re-render when their props or state change.
React.memo is a higher order component that memoizes the result of a component rendering, preventing unnecessary re-renders.
