    • Maintenance burden • Contribution barrier • Cross Platform Support
  3. None

  4. Meet Rust • Like C: compiled, statically typed, very fast

    • Unlike C: enjoyable to use, guarantees safety • "If it compiles, it doesn't crash" • Same guarantee as JavaScript with memory safety • Strong C/FFI support

  5. Cargo - Dependency Manager

  6. What is Neon? • Rust bindings for writing safe and

    fast native Node.js modules • Crash free memory protection (works with JS GC) • Parallelism (use multiple threads)

  7. Mandelbrot Demo

  8. None

  9. z n+1 = z n 2 + c
