When I was first learning about move semantics in C++, I kept reading articles that explained in terms of other scary sounding jargon — lvalues, rvalue references, memcpy, ownership. None of these things are strictly necessary to know about to understand the core of move semantics. (Though, the more you learn about them, the greater your understanding of move semantics will become.)

You may have heard of move semantics, and may know that they’re “faster”, but not why, or even how to move something. (Here “moves” and “move semantics” mean the same thing.)
