Can you describe a time when you had to resolve a performance issue in a Node.js application? What steps did you take?

In a recent project, we faced performance issues due to a slow-running API endpoint. I analyzed the code using profiling tools, identified bottlenecks, and implemented caching mechanisms to improve response…

🏷️
What is caching and how can it improve the performance of an API?

Caching is the process of storing frequently accessed data in a temporary storage area to reduce latency and improve performance. By caching data, APIs can avoid repetitive calculations or database…
