The `js!` macro allows embedding JavaScript code directly in Rust with serde integration for seamless data marshaling, as shown in examples like alerting messages and returning values.

Provides full access to DOM, events, canvas, WebSockets, and more, closely following JavaScript conventions, enabling Rust to handle web standards natively.

Leverages serde for serialization and supports exporting Rust functions to JavaScript via `#[js_export]`, making it easy to integrate with existing Rust libraries.

Compiles to WebAssembly using native backend or Emscripten, and to asm.js, offering performance benefits and flexibility for different deployment environments.
