Mastering C++ vtable internals: Demystifying polymorphism

This article explains how C++ implements polymorphism through virtual tables and virtual pointers, walks through their generation, memory layout, single‑ and multiple‑inheritance scenarios, distinguishes compile‑time and runtime polymorphism, and shows practical guidelines for when to use or avoid polymorphic designs.

Master Compile‑Time Polymorphism: Ditch Obscure SFINAE with C++20 Concepts

The article explains compile‑time polymorphism in C++, shows why traditional SFINAE is hard to read and debug, and demonstrates how C++20 Concepts provide clearer syntax, precise errors, and better multi‑condition support, backed by side‑by‑side code examples and a detailed feature comparison.

Compile-Time Polymorphism in C++: Implementation with folly::poly and dyno

The article explains how compile‑time polymorphism in modern C++—using libraries like folly::poly and dyno—can replace traditional virtual‑table based runtime polymorphism by employing small‑object optimization, compile‑time generated VTables, and type‑erased wrappers, delivering near‑virtual performance without inheritance or heap allocation.
