Cannot render boolean value in JSX?

You can convert boolean value to string, concatenating it with empty string:

var ipsumText = true;

ReactDOM.render(
  <div>
     Boolean Value: {ipsumText + ''}
  </div>,
  document.getElementById('impl')
);

Or you can do it, when assigning bool value to variable:

var ipsumText = true + '';

ReactDOM.render(
  <div>
     Boolean Value: {ipsumText}
  </div>,
  document.getElementById('impl')
);

If your variable can have not boolean value, you should convert it to boolean:

// `ipsumText` variable is `true` now.
var ipsumText = !!'text';

Boolean Value: { ipsumText.toString() }

or

Boolean Value: { String(ipsumText) }

or

Boolean Value: { '' + ipsumText }

or

{`Boolean Value: ${ipsumText}`}

or

Boolean Value: { JSON.stringify(ipsumText) }

I prefer the second option. Universal, fast, works for all primitive types: Boolean( smth ), Number( smth ).
