[ES6] Objects create-shorthand && Destructuring

Creating Object:

Example 1:

let name = "Brook";
let totalReplies = 249;
let avatar = "/users/avatars/brook-user-1.jpg";

let user = {name, totalReplies, avatar};

addUserToSidebar(user);

Example 2:

function buildMetadata(object){
  let id = parseInt(object.id);
  let lastUpdatedAt = object.updatedAt || object.createdAt;
  let hashCode = _buildHashCode(object);
  const isSecureHash = 32;
  
  
  return { 
    id, 
    lastUpdatedAt, 
    hashCode,
    isSecureHash() {
      return hashCode >= isSecureHash;
    }
  };
}

Example 3:

function buildTopicElement(topic){
  let title = `<h2>${topic.title}</h2>`;
  let author = `<small>${topic.author}</small>`;
  let body = `<p>${topic.body}</p>`;

  return { title, author, body };
}

Object Destructuring:

function buildMetadata(object){
  let id = parseInt(object.id);
  let lastUpdatedAt = object.updatedAt || object.createdAt;
  let hashCode = 16;
  const isSecureHash = 32;
  
  
  return { 
    id, 
    lastUpdatedAt, 
    hashCode,
    isSecureHash() {
      console.log("OK");
      return hashCode >= isSecureHash;
    }
  };
}


let id = 12,
    updatedAt: "Firday",
     obj = {id, updatedAt}

let {isSecureHash} = buildMetadata(obj);
isSecureHash();

From the code, we can see, besides object, you can also Destructuring function from the object.
