Yes, there are a few options for testing Rust and WebAssembly code locally. One way is to use the web-dev-server (<https://github.com/rustwasm/web-dev-server>) which provides a simple development server for serving and auto-reloading your Rust and WebAssembly code.

Another option is to use the wasm-pack CLI (<https://rustwasm.github.io/wasm-pack/book/>) which includes a dev server and other development tools for working with WebAssembly.

I highly recommend the Rust and WebAssembly book (<https://rustwasm.github.io/book/>). It's well-written and covers the basics as well as more advanced topics.

The Rust WebAssembly Working Group (<https://rustwasm.github.io/docs/wasm-bindgen/introduction.html>) has a lot of great resources, including examples and tutorials on using the wasm-bindgen and web-sys crates.

I learned a lot from the Browser WebAssembly tutorial (<https://developer.mozilla.org/en-US/docs/WebAssembly/Rust_to_wasm>). It's very hands-on and covers setting up a Rust project, compiling wasm, and deploying to a webpage.

It's not necessary to have prior experience with Rust, but it might be helpful. The Rust and WebAssembly book provides a good introduction to Rust, and there are also other good resources for learning Rust such as the Rust Programming Language book (<https://doc.rust-lang.org/book/>).

I'd recommend learning them together since they are so closely related. That way, you can learn about Rust's features, like its ownership model, that make writing safe and fast code for WebAssembly easier.

There are definitely benefits to using Rust and WebAssembly! Rust's safety features, like its ownership model and memory safety guarantees, can help prevent common bugs and security vulnerabilities in JavaScript and TypeScript code. Additionally, Rust's performance is often better than JavaScript and TypeScript, especially for computationally intensive tasks.

In terms of comparing Rust and WebAssembly to TypeScript and React, WebAssembly can be used as a low-level complement to JavaScript, TypeScript, and React, and Rust is a high-level language that can be used to target WebAssembly. So, you can use Rust and WebAssembly alongside React and TypeScript for the best of both worlds: high-level abstractions combined with low-level efficiency and safety.

There are a lot of cool projects that use Rust and WebAssembly! For example, the WebAssembly audio engine (<https://github.com/WebAssembly/bulky-web-audio>) is an experimental audio engine that targets WebAssembly and is written in Rust. Another example is the Yew web framework (<https://github.com/yewstack/yew>) which is a framework for building web applications with Rust and WebAssembly.

I know of a company that built their web-based CAD software in Rust and WebAssembly because they needed better performance and safety guarantees for their software. They've had a lot of success with it and it's been well-received by their customers.

It's true that Rust's compile-time safety can make debugging more challenging, but there are tools and techniques for working with it effectively. The Rust community has been working on improving error messages and providing more helpful debugging information. There are also tools like Rust's error index (<https://internals.rust-lang.org/error-index.html>) and the `error-chain` crate (<https://docs.rs/error-chain/>) that can help with error handling and debugging.

IntelliJ IDEA with the Rust plugin (<https://plugins.jetbrains.com/plugin/8182-rust>) is a good option for Rust development, and there are also Visual Studio Code extensions for Rust (<https://marketplace.visualstudio.com/items?itemName=matklad.rust>). For WebAssembly development, there is wasm-tool (<https://github.com/WebAssembly/wasm-tool>) which is a command-line tool for working with WebAssembly modules.

I personally use Visual Studio Code with the Rust (rls) extension (<https://marketplace.visualstudio.com/items?itemName=rust-lang.rust>) which has good integration with the Rust compiler and toolchain. For working with WebAssembly, the VS Code WebAssembly extension (<https://marketplace.visualstudio.com/items?itemName=mtklehr.vscode-wasm>) provides some helpful tools for working with WebAssembly modules.

Sure! First, you write your Rust code and compile it to WebAssembly using the `wasm32-unknown-unknown` target. Then, you can use the wasm-bindgen crate to generate bindings for your WebAssembly modules and use them from JavaScript or TypeScript. Finally, you can use the `wasm-pack` CLI tool to package your WebAssembly code and dependencies for deployment.

One important optimization is to use `no_std` and the `stdweb` crate for lightweight WebAssembly development. This avoids including unnecessary Rust standard library functions and provides lightweight replacements that are more appropriate for WebAssembly. Another optimization is to use `nightly` Rust, which provides additional performance optimizations and features.

You can also use the `inline-js` macro (<https://github.com/sunblaze-id/inline-js>) to write inline JavaScript in your Rust code, which can reduce function call overhead and make your code faster. Additionally, you can use wasm-bindgen's `preload_interface` and `export_shape` attributes to optimize memory management and function calls between WebAssembly and JavaScript.
