Can you explain how garbage collection works in C# and what you can do to optimize memory usage in your applications?

Garbage collection in C# automatically manages memory by freeing up unused objects. To optimize, you can reduce object allocation, implement IDisposable for unmanaged resources, and use memory-efficient collections when possible.

How would you optimize a GraphQL query to ensure it is efficient when fetching data for a machine learning model, considering that the model may require multiple nested resources?

To optimize a GraphQL query for a machine learning model, I would use query batching and ensure that I only request the fields necessary for the model’s input. Additionally, employing…

Can you explain what caching is and why it’s important in web applications?

Caching is the process of storing copies of frequently accessed data in a location that’s faster to reach than the original source. It’s important because it reduces latency and improves…

🏷️
Can you explain how meaningful names in your code can impact performance and optimization?

Meaningful names make code easier to read and understand, leading to fewer mistakes and faster debugging. While they don’t directly optimize runtime performance, they can improve overall development efficiency, which…
