Creating Refs

Refs are created using React.createRef() and attached to React elements via the ref attribute. Refs are commonly assigned to an instance property when a component is constructed so they can be referenced throughout the component.

class MyComponent extends React.Component {

constructor(props) {

super(props);

this.myRef = React.createRef();

}

render() {

return <div ref={this.myRef} />;

}

}
