1:46:34 actually thank you for making this video, studying is much more fun when youre doing it along with someone. Would really appreciate another more advanced one, I've learned tons with it!

[SwagBudder]

I was struggling to use javascript when it comes to solve problems, I followed a lot of tutorials and none of them helped me increase my ability to js, however, after watching this video, and solving the problems on codewars, I've started to get the hang of it and learnt soo much more than any other previous javascript tutorial. I love the way you went through each problem and explained and outlined the strategies needed to solve each of them, I really appreciate what you did, thanks!

[yuiheron]

I solved 20 out of 25 questions, some I solved on my own and some needed helped with it but thanks to that I learned so much on the process of it.

My first programming language is actually C++ for my university, I only learned the syntax and I couldn't solve problems without watching a video about it but now I can now solved a few beginner questions on my own, so the best advice here is don't be afraid on asking questions and you can always google if you are stuck with a problem.

I'll tell you whats the best part about this video. This guy is genuinely trying this for the first time with basic js knowledge and it feels like you are sitting with your classmate and trying to code. He is not a know it all kinda guy. Every doubt you have even he has it and he solves it looking at material online and thats just amazing. Most tutorials are like an automated chat gpt response where they go on and on without taking a breather.

[TechyMechie]

Very clear, to to point and the best tutorials ever on Youtube, cheers!

[devine_noise]

lol noped right out of counting sheet challenge. I've had a hard time finding this sort of teaching on YouTube. Thanks for making it.

[rockedwow]

I have a coding interview due very soon, and your video has really helped me. I challenged myself by completing the challenges on my own before looking at your solution, and it really helped me. Even tho you might see yourself as a small youtuber, just know you've made a fellow human confident with coding challenges. So thank you

Solution for counting sheep:
function countSheeps(arrayOfSheep) {
let counter = 0

for(let i = 0; i < arrayOfSheep.length; i++){
if(arrayOfSheep[i]){
counter += 1
}
}

return counter
}

[Miftaah-Ul-Islam]

one thing more I just like in your way of teaching to googling things. This is really a good practice to show people how to google..

KATA is Japanese for "the method"; or "the way of something" so The way of coding, or another translation the Coding method. Nice video btw found your video during a search for helping me with the solution for the chess problem on coding games. Watched your video to stimulate my problem-solving methods. Thank you!

[fahdbaig]

This problems to help beginners are so helpful. Previously i used to think code wars questions are a bit tough to understand, now you made it easy thanks.

[cubespeed]

Thanks for this Zach! I just got to the part where you thank the people who are still watching. Well, I haven't done it all in one sitting, but I will be watching the whole thing. It's been extremely helpful to me! I was really just stuck in the mud when I tried to start solving problems on CodeWars. This video got me past that hesitation, and now I feel much more confident to try and solve kata. Really appreciate you!

[moonfahim]

hey Zach, thank you! Waiting for more videos like this from you. Do some intermediate challanges this time.

[engsaydmohmedmahmuod]

actually the way you do is amazing no one is gonna say we have a problem lets google it so THanks

[slammerton]

21:06 Advices likes this are so valuable for beginners, thank you for that!

[robfarrell]

This is a great thing you did. I've been viewing a lot of tutorials over the last few years on Python, machine learning, HTML, but none of them have coding exercises like this. Brilliant!

[ravipratihast]

33:37 time frame -> Thank you for doing in a very easy way....!!!!

[twitch-clipz]

This is great information! I have an interview tomorrow and they said we were going to have these types of questions. I feel much more prepared, I just needed some confidence. Thank you Zach! Great video!

[jacobokomo]

This is the most beautiful thing I've ever seen under the sun.
Keep doing it buddy!
Explanations on point, I just destroyed the like button

Thank you so much for making this video! It's very descriptive and a great way to learn to code by following along. I appreciate your elaboration on the potential mistakes and tricky bits. Many thanks x
