Convert a c# request into Javascript

I need to convert this c# into a JavaScript request that can send an audio file via xhr as a chunked file. <code> var request = (HttpWebRequest)[login to view URL](requestUri); [login to view URL] = true; [login to view URL] = @"application/json;text/xml"; [login to view URL] = "POST"; [login to view URL] = [login to view URL]; [login to view URL] = host; [login to view URL] = @"audio/wav; codecs=audio/pcm; samplerate=16000"; [login to view URL]["Ocp-Apim-Subscription-Key"] = "YOUR_SUBSCRIPTION_KEY"; [login to view URL] = false; using (var fs = new FileStream(audioFile, [login to view URL], [login to view URL])) { // Open a request stream and write 1024 byte chunks in the stream one at a time. byte[] buffer = null; int bytesRead = 0; using (var requestStream = [login to view URL]()) { // Read 1024 raw bytes from the input audio file. buffer = new Byte[checked((uint)[login to view URL](1024, (int)[login to view URL]))]; while ((bytesRead = [login to view URL](buffer, 0, [login to view URL])) != 0) { [login to view URL](buffer, 0, bytesRead); } [login to view URL](); } } </code>
