Optimize a React function called every 5 seconds using techniques like memoization, useEffect, and throttling.

• Use useEffect to control when the function runs, ensuring it only executes when necessary.

• Implement memoization with useMemo or useCallback to avoid unnecessary recalculations.

• Consider using a throttling or debouncing technique to limit how often the function can be called.

• If the function fetches data, implement caching to prevent repeated network requests.

• Profile the...read more

I analyze logs, gather metrics, and collaborate with teams to identify and resolve elusive production issues.

• Review application logs for error messages or unusual patterns. For example, check for stack traces that indicate where the issue might originate.

• Analyze performance metrics and monitoring tools to identify anomalies. For instance, look for spikes in CPU or memory usage around the time of the issue.

Authentication verifies the identity of a user, while authorization determines what actions a user is allowed to perform.

• Authentication confirms the identity of a user through credentials like passwords or biometrics.

• Authorization controls access to resources based on the authenticated user's permissions.

• Solid principles refer to a set of object-oriented design principles like Single Responsibility Principle, Open/Closed Principle, etc.

Static routing uses manually configured routes while dynamic routing uses protocols to automatically update routes.

• Static routing requires manual configuration of routes while dynamic routing uses protocols to automatically update routes.

• Static routing is best suited for small networks with few changes while dynamic routing is better for larger networks with frequent changes.

• Examples of static routing protocols include OSPF and BGP while examples of dynamic routing protocols ...read more
