anyone has idea why this compile error?
when const in javascript is used wherever in js(), say like

js("const value = 5;")

it will complain missing ; before statement, is this a bug or I have some misunderstanding

I'm not sure that the ES2015 syntax is supported inside the js function. Will it complain if you replace the const with var?

[T8522192]

hmmm it work in above case, but in my actual case

@JsName("audioPlay")
fun audioPlay(url: String){
    js("""
            var context = new AudioContext();
            var source = context.createBufferSource();
            var audioBuffer = await fetch(url)
                .then(res => res.arrayBuffer())
                .then(ArrayBuffer => context.decodeAudioData(ArrayBuffer));
    
            source.buffer = audioBuffer;
            source.connect(context.destination);
            source.start();
    """)
}

it will complain the same error at the line of var audioBuffer = ... , maybe it can't be assigned for function

[Artem Kobzar]

await is also es2015+ syntax

[Artem Kobzar]

Try to run this:

var context = new AudioContext();
var source = context.createBufferSource();
fetch(url)
  .then(function (res) { return res.arrayBuffer() })
  .then(function (ArrayBuffer) { return context.decodeAudioData(ArrayBuffer) })
  .then(function (audioBuffer) {
    source.buffer = audioBuffer;
    source.connect(context.destination);
    source.start();
  });

It can be written in Kotlin/JS without redundant workarounds

Fine AudioContext is here

[turansky]

With coroutines you can use suspend fetch
