  let mut data = json!({ "x": 0 });
  
  // replace an existing key
  data["x"] = json!(1);
  
  // insert a new key
  data["y"] = json!([false, false, false]);
  
  // replace an array value
  data["y"][0] = json!(true);
  
  // inserted a deeply nested key
  data["a"]["b"]["c"]["d"] = json!(true);
