I learned a lot ...but this course is not for beginners. and there are things which can be improved like methods should be explained and why this method is used should be told vs other methods. Early beginners stay away.
By Akash keshari on 6/26/2025
Nobody taught me about time complexity pracitcal application in coding problems like this. Kudos!
By Sumanth Pai on 4/14/2025
1) When you declare your approach to be most simple , please also discuss about other approaches and its drawbacks this will inculcate critical thinking amongst learners and in actual interviews would help to choose an approach over the other 2) why to choose a particular pattern/strategy to solve a problem could have been explained in detail 3)resources attached here are of JAVA not JavaScript

I think he should prepare the classes before he starts talking. His notes are all over the place on the whiteboards he uses, which is a bit confusing. It is also too slow and I can't do speed 1.5x because I don't understand his accent

Revealing the mysterious world of algorithms in this course felt like figuring out old writings in today's world. Combining my JavaScript skills with LeetCode challenges helped me improve my problem-solving abilities a lot.
By Nabil El Fassi on 6/10/2024
Starting this course felt like going on a journey through the world of thinking and doing things well. Using JavaScript and solving problems on LeetCode, I gained a lot of knowledge and learned how to come up with creative solutions.
By Samira El Ouafi on 6/10/2024
with this class i found my way through a complicated maze with a really good guide. Every type of data structure was like a hidden garden, and the 100 LeetCode problems were mysterious puzzles that inspired me to become really good at algorithms.

very impressive course. with a comprehensive curriculum. He is a great teacher. I really enjoyed taking this course. I'm really happy I chose to take this class.It had a lot of useful informations. haven't finished the course yet , but so far so good.
By Clara Hobeika on 6/1/2024
This class is great. Now I really know about data structures and algorithms in JavaScript. I feel more confident about coding interviews because I have carefully studied the answers to over 100 Leetcode problems.
By Domenico Fenech on 5/29/2024
This class is great for learning about Data Structures & Algorithms in JavaScript from the beginning. The clear answers to more than 100 Leetcode problems will make a big difference in getting ready for interviews.
