// Setting up a data connection in JS using WebRTC is relatively straightforward. First, you need to create a RTCPeerConnection object. This object will be used to establish the connection between two peers.

// Create an RTCPeerConnection object
let pc = new RTCPeerConnection();

// Create a data channel
let dataChannel = pc.createDataChannel('dataChannel');

// Set up the ICE candidate handler
pc.onicecandidate = (e) => {
  if (e.candidate) {
    // Send the candidate to the remote peer
    sendIceCandidate(e.candidate);
  }
};

// Set up the data channel handler
dataChannel.onopen = () => {
  // The data channel is now open
  // You can now send data
};

// Create an offer
pc.createOffer().then((offer) => {
  // Set the local description
  pc.setLocalDescription(offer);
  // Send the offer to the remote peer
  sendOffer(offer);
});

// When the remote peer sends an answer
pc.setRemoteDescription(answer);

// When the remote peer sends an ICE candidate
pc.addIceCandidate(candidate);

// Now the connection is established and you can send data using the dataChannel object
