To deserialize the JSON string, we use the JSON unmarshal function. So we have our error variable just in case there's an error that occurs when we unmarshal. And we write JSON.unmarshal. We pass in our bite slice that we've casted to be when we pass in the JSON string, and then we also pass in a pointer to our products variable. We want to handle the error if it occurs. So, we will write an if statement that says, "if the error doesn't equal nil, we will return nil for the product and the error message."
