Here is IRB running in the browser by author of this feature

https://irb-wasm.vercel.app/

No installation required :)

Cute! But I get an error if I try "require 'resolv'", is this expected?

<internal:/usr/local/lib/ruby/3.2.0/rubygems/core_ext/kernel_require.rb>:85:in `require': cannot load such file -- socket (LoadError)

WASI doesn't support sockets yet, and in any case there's no browser API available to implement socket-level networking. Practical use of this would require bridging over to JS to implement HTTP requests and the like,
