Js_string, Arrays

[mationai]

Getting "[E4018] Type Js_string does not implement trait Show: method to_string is missing" building

pub fn hello() -> Js_string {
  "Hello".to_js_string()
}

Also, does moonbit provide easier interop of data structures like Arrays between wasm/JS? The method shown in WebAssembly/design#1231 seems like poor DX.

Sorry for the late response. The type Js_string is supposed to be opaque at the MoonBit side so it does not have the to_string method.

We are working on a solution right now. There will be a binding for JS API, and we may provide a conversion through memory copying. But for the most performant solution, you may have to wait for js-string-builtins
