Thank you for your blog article, it really helps me understand how does Linkedlist work.But I have a little question need your help, this is append code
`// Adds the element at the end of the linked list
append(val) {
let currentItem: LinkedListItem = this.head;
let newItem = new LinkedListItem(val);
if (!currentItem) {
this.head = newItem;
} else {
while (true) {
if (currentItem.next) {
currentItem = currentItem.next;
} else {
currentItem.next = newItem;
break;
}
}
}
}`
I think the “currentItem” is a block variable and do not return anything, but it really change the data of Linkedlist, what’s the relationship between " Linkedlist" and "currentItem" and how it works? It really troubled me for a week, thank you very much.
