You might have heard about linked lists, or you might think that you're supposed to know about them. Maybe you do know a little bit about them, but don't know why you should care or why they matter. Either way, I want to tell you about why they're so cool.
For much more on linked lists, check out the articles that accompany the video series:

As someone without a CS degree myself, and a less-than-stellar grip of some of these topics, this series excites me a lot. And I'm not just saying that because I helped make it 🙃
Super excited for this release! I'm both a visual and auditory learner, so this is perfect! 👌
Awesome stuff! Looking forward to the rest of the series 🙌🏼
Is there going to be a single url where I can discover the rest from? I thought it might be this page, but I guess this is just about linked lists?
This is just the linked list page, but @vaidehijoshi 's profile will have the new ones. If you follow her you'll get new posts in your notifications.
thanks!
This is great! One question: does the head node of a linked list contain data also, or just a pointer? I ask because you refer a couple of times to the second box in the linked list as "the first node," which confused me because visually it looks like the second node. And in the circular linked list, the tail node doesn't point back to the head. So this makes me think that the head node is "empty". Is that right?
Hi, Isaac, that's really good question. Hope I can help you. But yes, the nodes usually contain data. But it depends on what you want to do, you may need to use the 'head' just use it as a pointer, so it's not required to have data on your head node.
I. can't. even. explain how excited the prospect of this series makes me. I actually understand Big O now. Thank you! I'm sharing this with my team as we speak. Keep it up :)
so helpful, Thank you
This is a really great explanation Vaidehi. Very clear & easy to follow. I wish my teacher was as good as you, when I learned these introductory concepts.
Well done!
Yeah!
So glad that I've found this new series.
XOXO
Is anyone else experiencing issues playing the video? I am on Firefox (tried a few different networks).
Edit: Oh, videos do not work in Firefox!
Actually. Edit edit: Firefox seems to buffer the entire video before playback starts.
