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

What the code could have been:

// constants
const DEFAULT_ZOOM = 0.5;
const DEFAULT_WIDTH = 680;
const DEFAULT_HEIGHT = 400;

// interface for the parameters
interface BrowserWindowOptions {
  zoom?: number;
  width?: number;
  height?: number;
}

// function to open the browser window
function openBrowserWindow(url: string, options: BrowserWindowOptions = {}): void {
  // merge default options with provided options
  const mergedOptions = { zoom: DEFAULT_ZOOM, width: DEFAULT_WIDTH, height: DEFAULT_HEIGHT,...options };

  // validate options
  if (mergedOptions.zoom < 0 || mergedOptions.zoom > 1) {
    throw new Error('Zoom must be between 0 and 1');
  }
  if (mergedOptions.width <= 0) {
    throw new Error('Width must be a positive number');
  }
  if (mergedOptions.height <= 0) {
    throw new Error('Height must be a positive number');
  }

  // open the browser window
  TS.screen(url, {
    zoom: mergedOptions.zoom,
    width: mergedOptions.width,
    'crop-h': mergedOptions.height,
  });
}

// example usage
openBrowserWindow('act.com/nl-nl/producten/act-premium');
