The document discusses when and why to use Rust for web development. It notes that Rust provides performance benefits, easy integration of native libraries, and an opportunity to learn a new language. Specific advantages of Rust mentioned include guaranteed memory safety, easy parallelism, and its package manager Cargo. The document provides first steps for installing Rust and the neon CLI and outlines alternatives like foreign function interfaces and using Rust with Gopherjs. It also mentions a demo and caveats to be aware of like performance costs of calling Rust from JavaScript.

❖ Easy integration of native libraries
❖ To learn a new language

6. Benefits of learning a new language
❖ Expand your mind
❖ Deeper understanding
❖ Possibility to choose the right tool for the job
“Learn at least one new language every year. Different languages solve the same
problems in different ways. By learning several different approaches, you can help
broaden your thinking and avoid getting stuck in a rut.”
Andrew Hunt, David Thomas. The Pragmatic Programmer.

7. Rust
❖ Blazingly fast
❖ Guaranteed memory safety
❖ Easy parallelism
❖ Cargo

8. Alternatives
❖ Foreign Function Interface (FFI)
❖ Go (Gopherjs)

9. First steps
❖ Install Rust (https://www.rust-lang.org/en-US/install.html)
❖ Install neon-cli (https://github.com/neon-bindings/neon)
❖ neon new project

10. Demo

11. Caveats
❖ Calling Rust from JS comes with a cost, so make it worth
it.
❖ Be aware that if you use it on a library the users of that
libray will need to have Rust installed.
