find the average of all nodes in a linked list in javascript

To find the average of all nodes in a linked list in JavaScript, you first need to traverse the linked list to calculate the sum of all nodes. Once you have the sum, you can divide it by the number of nodes to get the average.

Here's an example implementation:

index.tsx
function calculateAverageLinkedList(linkedList) {
  let sum = 0;
  let count = 0;
  let currentNode = linkedList.head;

  // traverse the linked list
  while (currentNode !== null) {
    sum += currentNode.value;
    count++;
    currentNode = currentNode.next;
  }

  // calculate the average
  return sum / count;
}

In this implementation, we start by initializing sum and count to 0 and currentNode to the head of the linked list. We then traverse the linked list using a while loop, adding the value of each node to the sum and incrementing the count to keep track of how many nodes we've visited. Finally, we calculate the average by dividing the sum by the count and return that value.

Note that this implementation assumes that each node in the linked list has a value property that represents its value. If your linked list nodes have a different structure, you'll need to adapt the code accordingly.
