[Playground] AST viewer

[magic-akari]

I maintain the SWC AST Viewer. Unlike the current SWC Playground, it presents AST and token results using Rust-style formatting instead of JSON.

It would be more beneficial to integrate this functionality directly into the official SWC Playground. This would require exposing an additional debug output in the SWC wasm bindings.

I agree. I always check the code ast with swc ast viewer. It provides the ast info that is closer to the rust struct than the playground.

I think we can create one and document that it’s not a public API

Maybe debugFormatAST?
