tree traversal javascript

Comment

class Tree {
  constructor(root) {
    this.root = root;
  }

  // Inorder method doesn't need a root argument now
  // It uses instance's own root
  Inorder() {
    // Fire up the recursion
    Tree._Inorder(this.root);
  }

  // Private part for the Inorder method's recursion
  // It can be static since it will receive the root 
  // for each iteration
  static _Inorder(root) {
    if (root == null) {
      return;
    }

    Tree._Inorder(root.left);

    console.log(root.data);

    Tree._Inorder(root.right);
  }
}


class Node {
  constructor(data) {
    this.data = data;
    this.left = null;
    this.right = null;
  }
}

const obj = new Node(5);
obj.left = new Node(10);
obj.right = new Node(15);
obj.left.left = new Node(16);
obj.right.right = new Node(17);

const tree = new Tree(obj);
console.log("Tree created with root:", tree.root.data);

// Now we can call the inorder list for the tree 
// without explicitely specifying the root node
tree.Inorder();

javascript dom traversing

Comment

1.getElementById()
 <div id="user">Get Element by ID</div>
 const userId = document.getElementById(user)
 console.log(userId)

/* Output
<div id="user">Get Element by ID</div>*/

<!-------->
2.getElementsByClassName() 

<div class="user">Get Element by Class Name (1)</div>
const userClass = document.getElementsByClassName('user')
The getElementsByClassName() returns an array-like object of the elements.
We can convert the array-like object to an actual JavaScript array with the Array.from()
method or the spread operator.
/* With the Spread Operator */
const userClass = [...document.getElementsByClassName('user')]
