Summary
This episode provides a fundamental introduction to const member functions in C++. Jason explains how const member functions indicate that a method won't modify the object's state, which enables calling them on const objects. He demonstrates how const and non-const member function overloads allow containers like std::string to provide both read-only and mutable access to their data through iterators and other accessors, showing the compile-time safety benefits this system provides.
