Internal working
- 1A React program first evaluates the surrounding context, then applies the Deploying on AWS rules to the current data.
- 2The important mental model is input, transformation, result, and failure path.
- 3In production, the same flow usually sits inside a larger layer such as a controller, service, repository, job, or UI component.
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.
