How to Initialize a Linked List for Interview Problems in JavaScript (Leetcode) | Fast tutorial
In this tutorial, I show you how to initialize a linked list for interview problems that usually only require the head node. Hopefully by the end of this tutorial, you'll know how to create a simple Node class from scratch that you can use to build out a linked list, and get the head node only, without a giant Linked List class.
To speed up the process of initializing a linked list, I start out with an array and iterate through array values to create a linked list. There are many different ways to create a linked list, and this is just one of them! I also show you how to print out your linked list just by passing in the head node.
I noticed that there are many tutorials out there that explain everything there is about linked lists, and those tutorials are great! But I could not find many about the bare minimum amount of code needed to start some of these linked lists problems in your local IDE, like VS Code, which is what I use. So for those curious and wanting to set up your linked lists outside of Leetcode, this should show you how to do it.
