  // We use eslint-loader so even warnings are very visible.
  // This is why we only use "WARNING" level for potential errors,
  // and we don't use "ERROR" level at all.
  
  // In the future, we might create a separate list of rules for production.
  // It would probably be more strict.
  
  // The ESLint browser environment defines all browser globals as valid,
  // even though most people don't know some of them exist (e.g. `name` or `status`).
  // This is dangerous as it hides accidentally undefined variables.
  // We blacklist the globals that we deem potentially confusing.
  // To use them, explicitly reference them, e.g. `window.name` or `window.status`.
