screenfull.isFullscreen returns true when exiting fullscreen

[wiemann]

screenfull.isFullscreen doesn't return false when called in onchange event after exiting fullscreen

Go to the example page http://sindresorhus.com/screenfull.js/

Add this event binding in the JS console: screenfull.onchange = function(){console.log( 'Am I fullscreen? ' + screenfull.isFullscreen ? 'Yes' : 'No' );};

And now enter and exit fullscreen mode. On exit it will also return that screenfull.isFullscreen is true (Yes). How can one make it return the proper value?

It does, you need to wrap your expression in parens:

screenfull.onchange = function(){
    console.log('Am I fullscreen? ' + (screenfull.isFullscreen ? 'Yes' : 'No') );
};
