Difference between Pure and Function React JS component

React.PureComponent is similar to React.Component. The difference between them is that React.Component doesn’t implement shouldComponentUpdate(), but React.PureComponent implements it with a shallow prop and state comparison.

Function React component is that which accepts a single “props” (which stands for properties) object argument with data and returns a React element.
