What is a more concise/cleaner way to write this?

var data = (prop.noHeader === true ? 'noheader ' : '') +
    (prop.noFooter === true ? 'nofooter ' : '') +
    (prop.noBorders === true ? 'noborders ' : '') +
    (prop.noScrollbars === true ? 'noscrollbars ' : '') +
    (prop.transparent === true ? 'transparent' : '');
