Topics include: passing non-trivial types by const reference, using move semantics vs. copy, NRVO and guaranteed copy elision, string_view and span as lightweight alternatives, reserve() for strings and vectors, emplace vs. push/insert for STL containers, in-place construction for pair/tuple/optional/expected/variant, transparent comparators (std::less<>) for associative containers to avoid temporary string allocations, and moving constant data to compile time using constexpr. Clang-tidy checks and compiler warnings are highlighted throughout to help detect these patterns automatically. ## Full article daily.dev links to this article rather than hosting it.
