What are the best practices for using lambda functions in C++?

Some best practices include keeping lambdas concise, using captures wisely, and avoiding unnecessary copies.

Can you explain what captures are in lambda functions?

Captures allow a lambda to access variables from its surrounding scope. You can capture by value or by reference.

When should I use captures by value versus by reference?

Use captures by value when you need a copy of the variable, and by reference when you want to modify the original variable.

Are there any performance considerations I should be aware of?

Yes, capturing by reference can be more efficient, but be cautious of dangling references if the original variable goes out of scope.
