	// You need to implement a feature that behaves differently based on the user's role. Currently, there are 7 different user roles, and the logic is implemented using a series of if statements with some nested conditions. Here is a simplified version of the code:

	function handleUserRole(role) {
	if (role === 'admin') {
	// Admin-specific logic
	} else if (role === 'editor') {
	// Editor-specific logic
	} else if (role === 'viewer') {
	// Viewer-specific logic
	if (/* some condition */) {
