// Focus the new window popup.focus();

// Optional: Auto-clean reference when closed const checkClosed = setInterval(() => if (popup.closed) clearInterval(checkClosed); if (window.popupRef === popup) window.popupRef = null; window.open features

// Helpful features string const features = [ width=$width , height=$height , left=$left , top=$top , 'resizable=yes', 'scrollbars=yes', 'toolbar=yes', 'location=yes', 'menubar=yes', 'status=yes' ].join(',');

// Use it const win = window.open('/help', 'HelpWindow', getCenteredFeatures(900, 650));
