Tips

        
    
                            
  • Obfuscation can always be reversed by a determined person. Never put secrets or API keys in client-side code.
    • 
                            
  • Obfuscated code can be larger and slower, and may trigger security warnings.

                                    Does obfuscation protect my code?
                                    
It only discourages casual copying. Do not rely on it for security.
