如何使用 JavaScript 将元素添加到 JSON 对象？

var jsonObject = {
   members: 
   {
      host: "hostName",
      viewers: 
      {
         userName1: "userData1",
         userName2: "userData2"
      }
   }
}
console.log("A json object is defined as: ")
console.log(jsonObject);

console.log("Adding an element using the bracket notation")
jsonObject.members.viewers['userName3'] = 'userData3';

console.log("A json object after adding a property is: ")
console.log(jsonObject);

var jsonObject = {
   members: 
   {
      host: "hostName",
      viewers: 
      {
         userName1: "userData1",
         userName2: "userData2"
      }
   }
}
console.log("A json object is defined as: ")
console.log(jsonObject);

console.log("Adding an element using the dot notation")
jsonObject.members.viewers.userName3 = 'userData3';

console.log("A json object after adding a property is: ")
console.log(jsonObject);
