In this course, you'll learn **practical, project-based programming with Rust**, specifically tailored for someone who understands JavaScripts. 

Learning Rust can be daunting for a JavaScript developer because of differences like manual memory management, the compilation toolchain, the syntax, strong types and more.

While Rust has many great learn resources, like the staple _The Rust Programming Language_ book,  they often lacks specifics for developers coming from interpreted languages like JavaScript.

In _Rust for JavaScript Developers_ you will learn: 

* the fundamentals of Rust
* practical Rust project knowledge and 
* what the analogues are coming from JavaScript.

You'll get comfortable with developing in a new, challenging language and its environment. 

We'll use the Rust `std` library to make simple but non-trivial command line applications, and be empowered to read and understand the technical Rust documentation on your own. 

You'll understand the fundamentals of Rust syntax and tools like `Iterators`, pattern matching, `struct`s, `impl`s, and return types, and be able to use those in your programs. 

You will also be able to draw on your understanding of JavaScript to augment and better grok these new Rust concepts and ease Rust's notorious learning curve.

In this course, you'll be learning the fundamentals of practical Rust, from the perspective of a JavaScript developer.
