  // by the developer, leading to some exceptions in the code. That said it should be avoided.
  //
  // While the 'react-hooks/exhaustive-deps' rule is a good rule of thumb, it's not recommended to
  // automatically fix it from lint-staged as it can potentially break a legit intent.

  // Reminder that a good practice is to always declare the dependencies when using the hooks,
  // and if not applicable, add an eslint disable comment to the useEffect, useCallback... such as:
  //
  //    // eslint-disable-next-line react-hooks/exhaustive-deps
  //
  // Another approach can be to use hooks such as https://github.com/kentcdodds/use-deep-compare-effect to quickly bypass
  // shallow rendering limitations.
