helderburato profile image Helder Burato Berto ・1 min read

On this simple trick, I'll show you how to create a PureComponent as a functional way with React.memo.

// CLASS BASED - OLD WAY
class Button extends React.PureComponent {
  render() {
    const { text } = this.props;
    return (
      <button type="button">{text}</button>
    )
  }
};

// FUNCTIONAL

// With Function
function Button({ text }) {
  return <button type="button">{text}</button>;
};
export default React.memo(Button);

// With Arrow Function
const Button = React.memo(({ text }) => <button type="button">{text}</button>);
export default Button;
