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.

Thanks for watching!

I really appreciate all of your videos on react and git. The practical examples were all that i need. Thanks.

Ayo this isn't exactly what i was looking for, but it did clarify some stuff. Good shit.

I want to know more exactly how LeetCode specifically does it and it does similar to yours, but they just, show an array and call it what? I guess the head is just the first element of the array and that's what they're "passing" you but goddamn why do they say they're giving you the head, but write [1, 2, 3, 4, 5] instead of giving you the actual structure of the object!

bc then i have a hard time debugging and trying to work with the problems because I don't really know what can or cannot log

Much appreciated! Like you, I was looking everywhere for ways to efficiently setup VS Code for leetcode SLL problems . I thought it was just me :)
It was a pleasure to listen to you and thank you for a truly helpful tip!

great job 👍, can you please do a video on terminal productive commands for linux

[AkamiChannel]

Could you put it on pastebin or in the description so we don't have to type it out?

what is the purpose of tracking ‘current’ in

[sijanshrestha]

Please share the code in gist also if possible :) For some, its easy to read through code! Thanks

Jesus Christ 😭 wtf This video literally made this harder than it already is damnit I might as well just quit now
