How to show html entity using React?

I am wanting to show the 'cubic' html entity (superscript 3). I am doing like this:

const formatArea = function(val){
    return val + " ft³";
}

where formatArea is being called from inside the component':

render(){
    return (
        <div>
            {formatArea(this.props.area)}
        </div>
    );
}

but, the browser is showing it as ft&sup3;

Solution

  • Found this way using JSX:

    const formatArea = (val) => {
    return (<span>{val}&nbsp;ft<sup>3</sup></span>);
}
