Tips

  • URL encode query parameters before appending them to URLs — special characters like & and = will break the URL otherwise.
  • HTML encode user input before displaying it in web pages to prevent XSS attacks.
  • Unicode escape is useful for embedding special characters in JSON strings or JavaScript source code.
