I work on the quantum developer tools team at Microsoft. We put a lot of work into what we call the Quantum Katas to learn the basics via coding - https://quantum.microsoft.com/en-us/tools/quantum-katas

Our VS Code extension is trivial to install (https://learn.microsoft.com/en-us/azure/quantum/install-over...) or just try it entirely in the browser with Visual Studio Code online (https://vscode.dev/quantum/playground/)

To support that last scenario, where the language service, debugger, simulator, even package references, can run entirely in the browser, we built the whole thing using Rust compiled to WebAssembly, and our VS Code extension runs as pure JavaScript and Wasm. If interested you can dig into the implementation at https://github.com/microsoft/qsharp .

Happy to answer any questions!
