I think this tutorial could be improved.#153

This tutorial goes directly into language syntax and entirely skips things like how Rust passes and stores data. Maybe these things are mentioned later on but I lost interest immediately. The first things I want to know, as a senior dev, is how Rust passes by-value by default, move semantics, when data is stored on stack vs heap, ect. Followed by, how it manages memory and how it differs from c++. Basically, an overview on how the languages are different on a philosophical and fundamental level.
