Here is the full implementation.

/**
 * Definition for singly-linked list.
 * function ListNode(val) {
 *     this.val = val;
 *     this.next = null;
 * }
 */
/**
 * @param {ListNode} node
 * @return {void} Do not return anything, modify node in-place instead.
 */
let deleteNode = function(node) {
  /* replace current node's value with the same values as the next node */
  node.val = node.next.val;
  /* eliminate the next node by re-assigning the pointer that references it to instead point to the node after it  */
  node.next = node.next.next;
};
