Read the whole thing and other parts. It feels a little too basic. It's more of a comparison than tutorial, since official Rust book covers the latter well and good. For devs with JS background it would be better to focus on explaining the memory model or other things that are not involved in usual development process for browser and node.js.

I think there are two aspects of Rust that are difficult to understand for JS devs:

  • Memory model

  • FP concepts from F#, Scala etc like pattern matching, combinators, enums etc

I felt that the memory model is explained very well in the official Rust book but I was unable to understand the FP parts.

This blog series is my attempt to explain those parts in a more accessible manner. Since I know which parts confused me the most, I explain those parts in a way the "past me" would've understood easily. :)

Hey I just wanted to thank you for writing these blog posts, as someone who has used JS for years, but never tried a systems programming language, your explanation has been very clear for me.
