// 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 */) {
