Was initially sceptical to this but after skimming think this is actually a very good introduction. I do like the brevity of it compared to the walls of text in the official rust one. Although this does give an illusion that Rust is very simple/easy to learn but any beginner will find that anything more than "Hello World" or "2 + 4" is 10x more difficult than writing in a interpreted language. Not because Rust syntax is difficult but the constraints it introduce require more thought of the design of the program.

The article also skims over the single ownership model which is a big difference with Rust. And it does miss about creating macros, cells, threading & mutexes, heap allocated types, unsafe code, Rc, std::mem, and the whole crates and cargo ecosystem. Which is why I think this should have been titled "half-hour introduction to Rust syntax". Hopefully this does bring more people on the Rust train. I think 2021 will be a good year for Rust :)
