# E0376: JSX prop is missing an expression

Every attribute in JSX with a prop requires an expression:

    function Header({columns}) {
      return (<>
        <div numColumns={}>Name</div>
      </>);
    }

To fix the mistake, add a valid expression to the prop:

    function Header({columns}) {
      return (<>
        <div numColumns={columns}>Name</div>
      </>);
    }
