Question from the React (legacy) test

class ColorName extends React.Component{
    constructor(props){
        super(props);
        this.colorByCode={
           "#ff0000":"red",
           "#00ff00":"green",
           "#0000ff":"blue",
        };
    }
    
    render(){
        return(<span>{this.colorByCode[this.props.colorCode]}</span>);
    }
}

ColorName.propTypes={
    colorCode: PropTypes.string.isRequired
};

Check the valid proposal(s):
