• Using Websocket Channel in React

  I am working on a project where I have to make an api call to a websocket, and display certain information based on that call. As you can see I have used the subscribe portion of the channel in my call. Now I'm not sure what to do if anything with the 2nd two set of bracket. Do I need to include them my call as well, or do they come along with the subscription? And from which of them would I be using the information I need to display? In other words which one is the information I am recieving?

  

  '''

  const ws = new WebSocket("wss://ws-feed.exchange.coinbase.com");
  
    const apiCall = {
        type: "subscribe",
        product_ids: [
            "ETH-USD",
            "BTC-USD"
        ],
        channels: ["level2"]
    };
  
    ws.onopen = (event) => {
      ws.send(JSON.stringify(apiCall));
    };
  
    ws.onmessage = function (event) {
      const json = JSON.parse(event.data);
      console.log(`[message] Data received from server: ${json}`);
      
      
      };
