$TS.screen('act.com/nl-nl', {zoom: .5, width: 680, 'crop-h': 400});

What the code could have been:

typescript
/**
 * Displays a window on the screen with the specified URL, zoom level, width, and height.
 * 
 * @param url The URL to display.
 * @param options The configuration options.
 */
function showScreen(url: string, options: { zoom: number, width: number, 'crop-h': number }): void {
  // Validate input parameters
  if (!url || typeof url!=='string') {
    throw new Error('Invalid URL');
  }

  if (!options || typeof options!== 'object') {
    throw new Error('Invalid options');
  }

  // Validate required properties
  if (!options.zoom || typeof options.zoom!== 'number') {
    throw new Error('Invalid zoom level');
  }

  if (!options.width || typeof options.width!== 'number') {
    throw new Error('Invalid width');
  }

  if (!options['crop-h'] || typeof options['crop-h']!== 'number') {
    throw new Error('Invalid height');
  }

  // Implement TODO: add more validation for other properties if needed

  // Set the default width if the given width is too small
  options.width = Math.max(options.width, 400);

  // Create a new screen with the specified configuration
  const screen = {
    url,
    zoom: options.zoom,
    width: options.width,
    height: options['crop-h']
  };

  // Display the screen
  TS.screen('act.com/nl-nl', screen);
}

// Example usage:
showScreen('act.com/nl-nl', { zoom: 0.5, width: 680, 'crop-h': 400 });
