What are some performance tips for using C++ lambdas?

What are some performance tips for using C++ lambdas?

To optimize C++ lambdas, consider using capture by reference when possible, and avoid unnecessary copies.

Can you explain why capture by reference is better?

Capture by reference avoids copying the captured variables, which can save memory and improve performance, especially for large objects.

Are there any specific scenarios where I should avoid using lambdas?

Yes, avoid using lambdas in performance-critical sections where their overhead might outweigh the benefits, like in tight loops.

What about using lambdas with STL algorithms?

Lambdas work great with STL algorithms! They can make your code more readable and concise, but be mindful of their capture.
