💡Performance considerations
  • 1Choose the simplest implementation first, then measure real workloads.
  • 2Watch for repeated work inside loops, unnecessary allocations, and slow I/O in hot paths.
  • 3Prefer clear data structures and stable APIs before micro-optimizing syntax.
💡Security considerations
  • 1Treat external input as untrusted until it is validated.
  • 2Avoid hardcoded secrets and never print sensitive values in examples or logs.
  • 3Use established libraries for authentication, encryption, parsing, and database access.
