React manages forms using controlled and uncontrolled components, enabling dynamic input handling and state management.

• Controlled Components: Inputs are controlled by React state. Example: <input value={this.state.value} onChange={this.handleChange} />

• Uncontrolled Components: Inputs maintain their own state. Example: <input defaultValue='initial' ref={input => this.input = input} />

• Form Handling: Use onS...read more

Message delivery guarantees can be managed using techniques like acknowledgments, retries, and idempotency.

• Use acknowledgments: Ensure the sender receives confirmation that the message was received successfully.

• Implement retries: If a message fails to deliver, automatically retry sending it after a specified interval.

• Leverage idempotency: Design your message processing to handle duplicate messages without adverse effec...read more
