Learning Data Structures in JavaScript from Scratch

A really good way to learn Data Structures in JS for beginners.

The instructor has really helped me better understand data structures.

Great course to take if you're looking to brush up on data structures and algorithm.

excellent summary of structures Given the relatively brief duration of the course, the material was solid—definitely good for absolute beginners learning data structures.

This is a very important {key : value} data structure course linked to basic programming algorithms as well.

I wish he would have included other data structures though.

Eric has done everything great but there should be more data structures such as red black tree and Avl tree and graphs algorithims and much more topics well he has good and clear voice.

this is my first inception into the realm of data structures, and while I do not have much else to reference to for comparison, he does a fine job at articulating the concepts through practical code examples.

Good course but there isn't much data structures.

Clear easy to understand, covers important JS concepts and teaches you about data structures, this class is brilliant, I strongly recommend.

I didn't have any Data Structures knowledge.

whether you are starting out in Data structures or want a refresher this course will do the trick.

Excellently presented, well thought out to allow the concepts to be simple enough to quickly understand yet complex enough to allow me to use them in real life; easy to follow, Good instructor, good course material.

The course material is pretty thorough and easy to follow; I learned plenty!

Very easy to follow along.

Eric's explanations are great and were easy to follow.

It was very easy to follow along with the code.

Easy to follow along.

Very easy to follow instructions, and good examples and exercises.

Easy to follow, hands-on coding examples with detailed explanation!

Great course, and easy to follow learning methods.

Lectures are VERY easy to follow along and are not at all boring.

To me , this seemed a better way function User(name, age, gender) { return { name: name, age: age, gender: gender } } var josim = new User('josim', 26, 'male'); But, I can be wrong, Very nice and clear Well explained introduction that was easy to follow really good so far!REAALY GOOOD!

The explanation is very clear and easy to follow.

I liked how he showed how linked lists can be stored in memory as separate chunks, and I wish he touched on whether or not that was true for the other two data structures.

For me the course start to get's better after Linked Lists.

Learnt a lot, thanks, could be made much more helpful and instructive with a little more questions in the data structures like finding loop in a double linked list or least common ancestor in BST, just suggesting :) This course helped me lot about data structure concept.Thank you :) This course is is a good course if you getting ready for an interview but if you realy want to learn data structures this is too basic.

Diagrams would be helpful for some areas, such as adding/removing heads and tails from linked lists.

He did a great job explaining Linked Lists.

:) also, I hoped "inserting a node" (in linked list) would be covered.

The course started pretty basic with linked lists, but it's getting progressively interesting.

For example why is a hash table preferable to a generic dictionary (is it because to search a dictionary the run time would be O(n), because if you search for a key that is not in the dictionary you receive an error so you need to iterate through)?

I would've liked to see delete/remove methods for Binary Search Tree and Hash Table.

Can't wait to start the algorithm course tomorrow In data-structure course if we can add stacks and queues with the linked list,binary tree and hash tables.

I would've given 5/5 stars if the course had a bit more information regarding the call stack, since the way it functions was heavily used in one of the lectures, and if a remove method was implemented in the hash table and binary tree.

only linked lists, hash tables and binary tree search explained.

Some of his explanations, especially for for Binary Search Trees and Hash Tables, were dry and not thorough.

The section on Hash tables is especially good.

For example, how a hash table would work if the key is not a string (my guess would be to add a prototype method to the Object type which enables hashing for all the extenders, but I really would love to see your approach).

Talks about linked lists, b trees and hash tables in a way that can be understood by anyone.

Last exercise in Hash Table was a little unclear.

Definitely write the code yourself, this will give you a deeper understanding on how these data structures truly work.

All in all this course provided me with an excellent foundation for these data structures and I am eager to learn more and use them in my code.

The only extra thing I would have wanted in this course were better/more real world examples and use cases of these data structures; otherwise, this course was well worth my time and money.

He teaches the concepts well enough, and if you're struggling to understand these data structures and don't want to branch out into another language, this is good enough.

I enjoyed it and learned a bit This is the best data structures course so far.

Great course so far.

Good course, teaches fundamentals of javascript as well as data structures Enjoying the course so far.

The data structures are very easy to follow Very interesting data structures The data structures in this course are done really well A good course all around with practical data strucures Very good course on data structures in javascript Really good quality course, glad I signed up Very easy to follow course which is good Makes data structures easy to understand Teaching style is really good and clear Good quality course so far Good quality so far

The only critique that I'd give is that I would like to see more visual animations to help grasp the concepts that are explained.

I'd like to see the use of plain objects/composition instead of constructor functions.

Would like to see TreeNodes (not binary), Maps, Balanced Binary Search Tree Very clear...

As someone with no computer science background, I had difficulty understanding Data Structure; and believe me i tried about 7 courses and they were either fast paced or lacking depth.

If you are interested in learning more about computer science or data structures and algorithms, this is a wonderful first step.

These course makes me want to study computer science.

A good introduction for beginners to data structures/computer science or more seasoned developers that want to broaden their knowledge beyond built-ins.

As a developer that didn't study computer science I've learned a lot Great Course , straight and to the point .

For the first time recursion makes sense.

Simply example and clear explanation to understand better even at first time, thanks Not enough data structures.

It's the first time a tutorial has started with basics like constructor functions and lined lists.

The only complaint I have is that I would have appreciated more content on some real world content.

I particularly appreciated the practical examples of when you'd implement each data structure in the real world.

In addition, the examples are real world, which makes it easier to understand.

I particularly appreciated the comparisons to real world usage of this type of code.

great class but talk kind of too slow for me.

At times it feels a little slow, but I much prefer too slow than to fast.
