Linked List Data Structure | JavaScript

[@TraversyMedia]

I am a little rusty on algos, data structures, etc but would like to get into this type of stuff, let me know what you guys think about that.

[@Ath9394]

Yes brad please make a crash course or even better a whole data structure series. thanks

[@ytubelord]

Please Continue to do more. It makes us industry ready

[@lancerino765]

No, You are awesome

[@alaindimabuyo]

Im bad too when it comes to algorithms I keep forgetting about these things

[@TraversyMedia]

@@alaindimabuyo Yeah, they aren't things I use in my daily projects, however they are great for building muscle in that part of the brain :)

[@sushantkunkekar2155]

Hey Brad please upload Data structures in js crash course or big course ...please

[@andrewtelkamp1750]

Great video, thanks for taking the time to put this together this together @TraversyMedia! One small thing. For you insertAt() and removeAt() functions, I'm pretty sure you want to flip the sign and use an || operator to account for less than 0 values. `if (index < 0 || index > this.size)`

[@hectorserrano9314]

When I first watched this video almost three years ago I was completely lost and could never follow along. I took another shot yesterday and was able to understand it now. If anyone needs help, I will gladly set up a google meet call and explain it with a debugger trace if we need to. Just passing along what others have done for me in the past. Thank you Brad, this was a great explanation!

[@parashuramakulakarni5073]

Most awaited. Please do more videos on data structures.

[@Ath9394]

Hey Brad , just want to thank you for all the efforts you take for us.. Would love to have a series on data structure Javascript. Love from India 💓

[@Сергей-е4г5п]

From East Europe too)

[@rakeshreddy1365]

from india too

[@network9990]

I wasn't able to understand all of this after weeks in a computer science course, but 30 minutes into your video I have a much better understanding. You are great at explanations and don't over complicate topics. Thank you so much for this video!

[@chocolate_thunder_04]

Can you do queues, stacks, trees, graphs, recursion? if possible Just a whole series on Data structures and algorithms

[@emilewamsteker3412]

This dude is a genius. Not just as a developer, but as a teacher. Thanks, Brad! Data structures is by far the most significant hurdle in programming, and I haven't been able to find anyone who can explain the concepts at a level I can understand. It's hard to teach concepts that are basically abstractions built upon abstractions. But from all the resources I've looked at, Brad has come closest, and in JavaScript no less. Bring on more data structures!

[@dm.hol.3624]

nah, his voice is quite boring, it sounds like he wants to just close the editor and throw his monitor out of a window. There is an example of a good teacher/programmer - "net ninja", I strongly recommend to look at his videos.

[@vijayroy7634]

you just blow it!!!! How you even do it ....I must say you are X-MEN Mutant YOU JUST MADE LINKDLIST SUPER EASY WITH MOST CONFUSING MODERN JS WOW

[@fromillia]

Brad i realy don`t understand why you don`t have at least a million subscribers. You're one of the best youtube IT-blogers (for me you`re the best).

[@robertmacdonald3773]

I'm a Full Stack student and just wanted to thank you for this video! It really helped me wrap my brain around the concept of Linked Lists👊🏾

[@goldenfibonacci7860]

thank you for always being straightforward and keeping it concise. Been watching your videos and following your tutorials for the past year and they have been an immense help. much love from California!

[@Balowulf]

Excellent introduction to a new topic for me! One edge-case we're missing here for the insertAt() method is a negative value being passed as the index. I found that this can be better handled by setting up the "index out of range" conditional to be: "index < 0 || index > this.size", so we simply return (do nothing with the data value) if the index is less than 0 or greater than the size of the linkedList. In my testing that gives us the functionality we want, without a resulting "Cannot set property 'next' of undefined" if a negative index value is passed.

[@bobbymcgee723]

I think it's great that you've started getting into this topic. I've had a lot of trouble reading about this stuff and then implementing it. But seeing it from you, then thinking about it for a bit, then going back and trying it myself, has really done the trick.

[@alexanderpotapov2774]

that's a great example of creating and working with Linked Lists on JavaScript. Thank you

[@MeshTheSnake]

the goat, feeling much more comfortable with LinkedLists after this video. Thank you.

[@sultanhoodie5495]

the best video i have seen about linked lists, simple and straight to the point. Well done.

[@moayedmustafa9673]

Dude this should indeed be a series, best explanation ever on this topic

[@Ash-em5pm]

Quite glad that you are getting your feet in core CS . It's a rabbit hole from here on and it's really fun as you start diving deeper.

[@poka247]

You make learning so much easy. Really appreciate you taking the time to make me understand this better than most tutorials out there!!!!

[@fanwilliam7725]

Thanks for the tutorial, I was doing an exercise from Odin Project and can't seem to wrap my head around this list. Your demonstration was very helpful, once I figured out the head variable was the key to this linked List structure, I picked this up real fast. Thanks!

[@blaquebeardcoder]

This was very helpful! Today we are learning LInked Lists and React in bootcamp, and this is a great prep for class tonight! Thank you for creating this content!

[@nanonkay5669]

Bro, do all the data structures PLEEEEEEEAAAAAASE. I've been looking for videos that discuss data structures and here you are. God sent. Please do more. Pleeease pleeease

[@LenTos1337]

Initially i did this data structure on my own and then watched your implementation, and this really makes your brain find different solutions

[@vaibhavmavani1071]

// Insert at index insertAt(data, index) { // If index is out of range if (index > 0 && index > this.size) { ---------this line should be like this----------> if (index < 0 || index >this.size){) return; }

[@chanduallada2417]

I checking for this comment :)

[@badmusadeyinka1662]

That'd mean it won't insert when index is greater than zero even if it's less than the list size. if (index > 0 && index > this.size) is correct.

[@malibaturhan]

Best tutorial about linked lists. Not just for JS. I searched for java too and this is the best I saw. Since there is just some difference in syntax every c# or java programmer should watch this too.

[@nicolegathany9626]

I laughed in this coffee shop when you said, "But don't be a dick about it!" Haha!

[@frankie_goestohollywood]

Me too..that was great!!! :-)

[@vincentadeniji6403]

and here I thought it was only me rofl.

[@MyOsmancan]

You taught so much about something so difficult, even to people like me who don't understand clear English. Amazing! Thanks for simple explanation dude

[@buncha1499]

Of course as i've been getting into linked lists, here Brad is with a brand new course on it, love it!

[@irhamputra3666]

Thanks Brad, you did an amazing job again. Finally you did data structures and algorithm 👏🏼💪🏻

[@rajeshchauhan657]

Great tutorials , sir You made me a real Developer.

[@bradliu1891]

Hi Brad, I've been watching your video for years. A little surprised seeing you started algos and data structures. Thanks for sharing. Love you, your Chinese fan.

[@AnatolioMoskalenko]

Thx you saved my life... I had a project to do for tomorrow and I knew nothing about that ... I was doing Java but the options are the same so thank you very much

[@maciepyou]

this brings me back (comp sci degree, but never got a job at it)...good stuff! I think maybe for inserting at index the bound check could be index < 0 || index>size? although using a negative index to insert from the end would be a fun exercise too.

[@erickchavez4551]

Thanks a lot for taking the time to explain this. I've been having a difficult time understanding the logic behind linked lists, but now I feel like I am getting it :)

[@randydiebold325]

Thank you for doing this. Please do them for all of the Data Structures. This will be super useful for people try to start out

[@rajsaroj4696]

First 10 mins was all i needed, my professor couldn't explain this in 3 hrs.

[@eldonratzlaff]

Line 93 change(index > 0 && index > this.size) to if (index < 0 || index > this.size)

[@itsshopboy]

Can't wait for that. The normal projects have become quite popular here on KZbin

[@tom-badger]

Shouldn't early return condition be like (index < 0 || index >= this.size) ? Otherwise if you pass negative value as index it will pass through range check and break data structure.

[@nd6439]

More algos + data structures please! Also some techniques + tips and tricks on how to solve problems. Your tutorials are very informative and easy to understand.

[@rickrieger1495]

"Don't be a dick about it" I love how honest you are man...

[@MULTICODE]

haha i'd been doing this in school algorithm and data structure, we used to implement double linked list. great to see that you jump into it. this course is really cool and understandable. great work . Love From Cameroon

[@jonesgabriel9337]

This video was super helpful and informative. thank you Brad!

[@pablitoengineer]

Hey, Brad, nice explanation. Thanks a lot for this excellent video. I would like just to make a small correction. It seems your range validation is not totally right. You wrote: if (index > 0 && index > this.size), but it will fail passing negative indexes. I believe the correct would be if (index < 0 || index > this.size). What do you think?

[@akintaylor2414]

Hey Brad thank you so much man. It's important you know your work is helping people out here. I am more confident in my Javascript cause of your course.

[@ytubelord]

Finally some data structures Thanks

[@kirant9339]

Hey Brad , just want to thank you for all the efforts you take for us.And please upload the important topics of javascript in the point of interview please.

[@TheYogeshkulkarni]

Thank you Brad. Aye for the series on data structures and algorithms. I watch your videos for dual purpose, to learn and to fall asleep.

[@blasttrash]

r u implying that his vids are boring? :P

[@TheYogeshkulkarni]

@@blasttrash Naah man :), videos are damn good and informative, but he has this amazing white noise like voice, so if you watch during the night, you will fall asleep in no time. Try it :P

[@thaungthanhan5928]

This tutorial made linked links easy for me

[@ahmedouyahya]

This is my getAt method, if you find it more clear: getAtIndex(index){ if(index>0 && index>this.size) return let count = 0 let currentNode = this.head while(count

[@kylegashler5995]

I think that you flipped your comparator on line 46. I think you meant to look like ` if (index > 0 || index > this.size) {` which would account for possible negative indexes provided, whereas checking for positive indexes seems like the case that you are looking to execute on.

[@hliasfasilakhs6765]

Amazing man. Thanks for everything. Trully amazing. i grasped everything after carefully watching the video

[@mikevaleriano9557]

@ 7:10 I saw you almost naming your method insertHead.

[@MarkDyck]

Sweet. This takes me back to my university days. Love it!

[@josiah7686]

Nice LL overview that is easy to follow and understand. Thanks!

[@codingfox]

Please, more videos about algorithms and data structures

[@rachkashyap]

At 15:05, for the method insertAt(), shouldn't the edge case be if(index < 0 & & index > this.size)

[@narendrajoshi5460]

Thanks brad for your efforts. would love to have a series on data structures and algorithms.

[@620026200]

Thank you! Your video is even better than a book i bought

[@siddhantjain2402]

Hi Brad. I have a question. I have seen a lot of companies focus on Data Structures and Algorithms in their Placement Tests but having worked with some tech companies I have never seen much use of DSnA. Most of the work these days is already done for us. Then why so much focus on DSnA? Could it be that I am just not at that level..?

[@jansherkhan590]

Hi brad Sir, without watch this video because I know you always bring great stuff that is easy to learn. I am greatfull you.

[@arditgjondedaj6143]

Programming itself is an algorithm and this is useful. Thank you !

[@pawanrk4818]

Hey, I came across ordered and Unordered Linked Lists. So what is explained in the video is which type of LL ? And does ordered means that they are indexed or contiguous ? Please help.

[@kunaljoshi8038]

Thanks Brad! This is a good video. Looking forward to learn data structures and algos from you :)

[@bodolawale5448]

Thank you Brad. You are turning me into an awesome developer.

[@antoniovaldenisiobezerraju2550]

Thanks for this new lesson! I loved it. I would thank much more for other lessons about those programming core subjects applied to JavaScript.

[@yaniasari4716]

15:49 "Just don't be a dick about it please." LOL! Thanks for being a real one Brad, and for always producing easy-to-follow videos.

[@stevemiller123]

The way you wrote the Remove method would make it impossible to delete the first item in the list. Here is a version that would let you delete the first item: remove(index){ let current = this.head let previous let count = 0 if (index === 0){ this.head = current.next this.size--; } else{ while (count < index){ count++ previous = current current = current.next } previous.next = current.next } this.size--; }

Hey Brad. Great video. I notice a small problem(?). You use "if (index > 0 && index > this.size)" but if we pass a negative index, the application will throw an error. Instead of "if (index > 0 && index > this.size)", we could use "if(index < 0 || index > this.size)". What do You think?
