Do you want to see more videos with a technical "interview prep" focus? Usually I cover practical projects, so curious to know what you think...
YES please! Much love!
I like this videos more than others
Yes interview preparation, this one is awesome
YEEEEEEEEEEEEEEESSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS
Yes!
Thanks, with my 6 years+ experience as a Frontend-dev, I now feel like a junior-dev again 😅
you just said it!
I would love more algorithms, data structures, and ML too!
+1 for the "x in 100 seconds... but wait there's more!" format. Getting a brief overview of the concepts followed immediately by a more in-depth implementation of those concepts is a fantastic way to structure the video.
I would’ve needed this for my computer science class 😫😫 Once again your content is the high quality learning we all needed
In my case , it is right on time.
This is a basic topic in a first semester computer science class.
IF CS WAS A MOVIE THEN
THIS MAN YOU WOULD BE THE AUTHOR
Movies have script writers and directors as key creative roles. No authors.
100%
I'm writing a screenplay titled "CS - The Movie" ;)
Fireship, I'll definitely watch it.
Greetings from Tanzania 🇹🇿
another Ali gate fan here
Definitely want Algorithms, Design Patterns and Data Structures 🙏
So glad. While these X in 100 seconds videos are great for some topics, this definitely needed a longer one.
Thanks! Yeah, trying to decide if I should make them as completely separate vidoes
Fireship I’d certainly love that! But honestly, anything you put out is gold. You’re on fire.
@@Fireship Maybe release them simultaneously so that people who want can watch both and there is a higher chance of one going viral.
@@Fireship Please make this type of video with a slow pace. Your teaching style is good. but just take longer and bit slower-paced videos. Give some time to grasp the concept along. However, like these videos. Thanks!
Fireship Yeah, I think u definitively should do that. Some of your viewers want more in-depth information and with a bit more time to consume it. So I think it is a good Idea to do a 100 secs version and a in-depth version. Anyways I really appreciate your work and passion. Thank your for your vids. Have a nice day. :D
Every time the outro music fades in, I can literally feel that 'i get it now' rush ! Thanks a lot and keep up the outstanding work !!
I really appreciate this format especially the combination of 100 seconds & beyond 100 seconds
That was sweet!
Please create a playlist of data structures and algorithms.
Great content, keep it up 👍🏻.
🔥🔥🔥
5:32 Javascript destructuring in 100 seconds
more like JavaScript de-structuring in 100 milliseconds.
This video is more than worth of my three year CS degree 🔥
100 seconds of different time complexities as in the Big-O-Notation would be awesome. I tend to forget how they work when I haven’t dealt with them in a while (same with Regex) so I think a 100 second reminder would be perfect!
In 10 Min, I came out with a better understanding of graphs then I have in the previous attempts (which was a lot). Thanks for making graphs make sense.
I love this! Very clear explanation. I would love a mix of project videos and interview ones like this.
Wow! This is awesome 🙌 would love to see more of this!
This was amazing! Great speed, great length, great everything!
This video is awesome! I love seeing these 100 second videos pop up in my feed, they’re always fantastic. One note though: an adjacency matrix does have very bad space complexity, but part of the reason for that is that it’s making the trade-off for time. It actually is quite time efficient to check specific connections [O(1)], so it just depends on what your program is prioritizing or needs.
I really enjoyed working with these data structures and algorithms in JavaScript. I would love to see more of this!
Great timing, would definately love more videos like this!
This is great. Best implementation of DFS / BFS I have seen in a while. Thanks.
Some people were really born to teach.Congrats
You've made this one understandable enough for a person who hasn't yet got to this part of programming. Solid introduction to the topic. Didn't get everything, but the idea is very clear. Cheers!
I can't believe I'm watching this in my leisure time. This is quality content! Keep them coming. Would love to see more algorithms explained like this. Thanks buddy, you're a rockstar! :)
Awesome job! Thank you. 100 seconds is great no complaints but beyond is next level!
Thank you！This taught me more in a few mins than my professor in hours!
I needed this for my computer science class , your content is the high quality learning we all needed
Yes, I would definitely like more videos with technical interview prep focus. I'm probably a ways off of an actual interview, but it's nice to mentally prepare proactively because I'm such a good procrastinator!
This hooked me like crazy. Please do more data science and algorithm videos like this. Loved it!
This is really nice. Also try making the speed 2x and watch it like 3 times if you want to overclock your brain. But it could cost you a few more seconds tho :/
😂
Finally somebody explaining Algortithms with Javascript Sets and Maps! Thank you.
It's crazy how much I learn from your videos in such a short time. Thanks you are the best.
this actually just helped me in a FANG interview, great stuff!
That was awesome, keep it up with more advanced stuff
this makes so much more sense than any CS video i've ever watched
Make all 100 seconds videos like this, a 100 seconds explaining everything simply, then go into details...this is awesome
This was incredible! Finally a real world example where you show the power of recursion 🙌
fireship does youtube like no other channel
the "basics in 100s + deep dive" format is a blast, man
Very clear instructions. I only know Python and I completely understood your coding process with Javascript.
This content is GOLD. Tyvm
It is so nice knowing that you decided to use recursion instead of stack in DFS to show to show it can be down either way. Thanks a lot Jeff 😍
Amazing, as usual. It’d be awesome if you created a full course on algos. Thanks! 😃
Yes, definitely want more data structures and algorithms videos like this! Thanks for these videos, I wish I would’ve had you as my CS Instructor 😂
Thanks for taking the time to make this great video! I'm doing interview prep, like many others. There was a problem I ran into while recreating breadth first search graph traversal: the enqueue in the 'bfs' method was happening regardless if the destination was in the visited Set so I ran into an endless loop scenario. I removed that and just kept the enqueue in the 'if not visited' statement and I get the correct answer. Please forgive if I just missed some of the code in the tutorial and thanks again for the great video/succinct example!
Hellllll I loved this video. THANK YOU!!! This channel is seriously awesome. One of the best coding channels in the entire internet. ❤
Bro! The way you explained this and the neatness of your codes I could grasp the Graph theory quickly. Please make a series.
Would be great to do more of these technical "intervew prep" videos. Awesome explanation! Sums up half semester of Algorithms course :D
When I say I was stressing! This just saved my life thank you.
Greatest explanations i've ever seen on TH-cam hats off @fireship
If only I knew that Javascript was this complex before I would have paid more attention to it. I'm a backend developer and thanks to your videos I have been slowly getting better and more interested in Javascript. Awesome work as always keep up these explosive contents!
3:25 "go slowly and explain every step!" while going on for 10½ minutes like an absolute rap god xD Had to watch the video back to back twice and still only got half of it, but loved all of it ^^
Another great video! Please continue
Loved this. 100 seconds to grab attention and beyond for serious developers
This is great! Just what I needed!
one of my favorite videos so far!
The format of these videos is brilliant! 100 seconds intro and then, if you want it, some practical implementation.
great video! quick and efficient refresher for stuff i touched 10+ years ago when i did my bachelor's. thanks :)
+1 for more algo/ds in JavaScrip! Amazing content.
Been enjoying your content for years, Jeff. Wish I had you when I studied CS :) Suggestion: Sort algorithms for DBs and why they're useful in different scenarios.
I didn't know I needed a fireship video about cs theory until I watched one. Plz do more
This is such a great video!Thank you!!!!
This is by far the best explanation of node.
straight up one of the best channels on yt
This is awesome, please keep it going 👍 , need more of these .
i love your channel for a long time. content and form are premium. i confess i was not so engaged with 100 secs videos. seemed hushed. this approach with 100 secs as intro to something more in depth following is perfect to me. thanks for such great work.
Thank you so much for sharing very high quality contents!! More CS topics pleaseee :)
Great explanation as always, thanks! 👊
Very good quality content! I love it! need more videos like this....
Amazing video!! Practical problems are ALWAYS better than abstract ones.
OMG, this video actually solved the programming problem that I am having today! Just my luck, thank you so much.
Thanks man , I used to fear from this topics , you made so easy that any non tech guy can understand completely . God bless you 🙏
This is really cool! More traversal methods please!
wow so fantastic, so fast and all necessary details/CRITICAL details are covered with real time application.
This really makes me so excited to dig deeper into the topic.
Keep posting more informative videos like this.
And could be also attach code in the video description in popular 3 languages like python, Java, c++ along with javascript
You just saved me a ton of time. Thanks for the video. :) Keep it up.
Great video. Would love to see more!
thank you, will be practising a lot
This reminds me of one of the first excersices of the book "eloquent JavaScript", it was awesome!
Wow brilliant tutorial man brilliant lesson thanks so much learning so much here
Great stuff! Thank you for the content!
This video was a majestic thing of beauty.
Thank You So Much for this wonderful video...🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻🙏🏻
yes please we want to see more videos like this!
Love the beyond 100 seconds part!
Please provide us with more algorithm, data structure videos which also focus on the interview perspectives, like this video did. Love your efforts man!!! Thanks
That was great. I would like to see more of these. And also the thought process that takes place when you should use a Map..how to effectively use maps
Awesome 👏 everything can be explained in 100s
Sooo cool dudee!! I really take my notes and learnt from your explained
Thank you so much. Please make more and more videos on Data Structures and Algorithms. Thank you once again!
Thanks you so much for this video ❤️ you are a life saver. I will need more of this video.
you are Saviour of cs students 🙇♂🙇♂...
Amazing content. Thanks !
I had to figure all this stuff out on my own when trying to implement A* pathfinding in a game I made. The tutorial I followed used an adjacency matrix. But my game maps were 1000 x 1000. The whole thing crashed when it tried to build the matrix. So I manually went through and converted the graph to a list structure, so only nodes with edges were stored.
I guess I could have saved the whole thing to the hard disc instead of keeping the whole graph in memory at run-time, but I learned a lot fixing that problem.
Keep up with the great content man
Amazing one.. WE need more of these :) Bring it on brother ✌
Not gonna lie, have an interview coming up and this was amazing, thanks so much for sharing the knowledge
For anyone that didn't see how you get the steps at 9:49 it's `DFS found Bangkok ${visited.size} in steps`. Use the visited size.
This channel is a gem
Sure this is awesome❤️ we definitely need more of these
At least it will help us cracking the coding interview
Great video. You should totally do a whole series of fundamental CS concepts.
