How to get bytes from JS Blob

Support
1

I cannot figure out how to get to raw bytes from Blob (org.w3c.files.Blob). Kotlin JS representation of Blob does have any suitable method :frowning:

UPD. This code seems to be doing the job:

       if (data is Blob) {
                println("Data is Blob! ${data.type}")
                val reader = FileReader()
                reader.addEventListener("loadend", {event: Event ->
                    val r = reader.result
                    if (r is ArrayBuffer) {
                        println("Data is read as ArrayBuffer")
                        val arr = Int8Array(r as ArrayBuffer, 0, r.byteLength)
                        println("Data byte length: ${arr.length}")
                        handler(arr as ByteArray)
                    } else {
                        println("Data is read not as ArrayBuffer")
                    }
                })
                reader.readAsArrayBuffer(data);
            }
