i think it should be very clear what getImagePath returns so we just make sure it's gonna return a string or null and then the long version becomes this:

const getImagePath = () => return 'path_to_image.jpg' || null;

    const path = () => {
      const imagePath = getImagePath();
    
      if (!imagePath) {
        return 'default.jpg';
      }
      return imagePath;
    }

The short version is good.
