Top 7 Courses to learn Data Structure and Algorithms in 2024 - Best of Lot [UPDATED]

Hello guys, both Data Structures and Algorithms are one of the most essential topics for programmers and if you want to learn Data Structure and Algorithms in 2024 then you have come to the right place. The best thing about them is that they never get out-of-date, and any investment you made in terms of time and money will pay rich dividends for a long time. I have also found that people good at algorithms and data structures are often better programmers than others. They tend to improve your programming skill and coding sense, and that's the main reason I suggest all kinds of programmers, from junior to senior to spend some time revising, refreshing, and honing their data structure and algorithm skills.

Most of us first heard about them in school and colleges but didn't understand at that time. At least I can say that to me. I first heard about the array and linked list of my engineering college. At that time I didn't know what is the use of an array and linked list because most of the questions we face were based on theoretical knowledge without any practical application.

For example, the difference between an array and a linked list was a sure-shot one to appear in the exam, and just mugging the answer was enough to score well. It may be possible that you might have better learned them myself in your college and school, but that's a general pattern.

I first realize the real use of array when I was writing games for mobile devices in my first company. I was tasked to write a board game, and then I found that I can use a two-dimensional array as a board and just store 1 or 0 to indicate whether a particular place is occupied or not.

That was my first real-world experience with a data structure and how they play roles in real-world applications. I know it came quite late, and I was lucky to find my way without knowing much about data structure, algorithms, and programming in general, but that was the ting of the past.

Nowadays, the environment has become very competitive, and you just can't afford to miss these critical concepts. You also need to be more proactive with your learning than the past generation was.

If you are one of them and actively looking to learn algorithms and data structure and looking for some excellent courses to start your journey, then you have come to the right place. In this article, I am going to share some of the best data structure and algorithm courses for Java, Python, and JavaScript developers.

7 Best Data Structures and Algorithms Online Training Courses for Programmers in 2024

Many of my readers were asking me about data structure and algorithms courses on various programming languages, mostly in Java, Python, and JavaScript.

I told them that data structure and algorithms are general programming concepts and once you are familiar with concepts you can work in any language, but with my little interaction with them, I realized that people know more about a programming language like Java or Python than a data structure like a linked list or binary tree.

That's why it works best for them if data structures and algorithms are explained and implemented in the language they know better.  That makes sense to me, and that's why I have included data structure and algorithm courses on these three programming languages.

But, even if you don't use those languages, you can still benefit from these courses because ultimately, data structure and algorithms are generic, and they are just concepts that can be implemented in any language. Any, here are the best courses to learn Data Structure and Algorithms in 2024

1. Data Structures and Algorithms: Deep Dive Using Java 

This is one of the most comprehensive courses on data structure and algorithms using Java.

It provides an excellent and straightforward guide to implement the most up-to-date algorithms from scratch: arrays, linked lists, graph algorithms, sorting, etc.

You will also learn about binary trees, balanced trees like AVL trees and red-black trees, heaps including heapsort algorithm, and associative arrays and dictionaries.

If you are a Java developer and looking for an excellent data structure and algorithm course, then you should join this best data structure and algorithms course on Udemy. It's comprehensive, but at the same time, both exciting and challenging. If you want to learn Data Structure and algorithms in Java then I highly recommend this course.

2. Master the Coding Interview: Data Structures + Algorithms by Andrei Negaoie

This is another awesome course to learn Data Structure and Algorithms for coding interviews. Yes, most of us turn to learn Data structure and algorithms when a coding interview comes but a solid knowledge of Data structure and algorithms goes a long way and helps you to design a better system in your day-to-day job taught by Andrei Negaoie.

If you don't know Andrei is one of the most experienced software engineers and also one of the best-selling Udemy instructors. I joined many of his Python and JavaScript courses which now you can find in his ZTM Academy (Zero to Mastery Academy) 

In this 19.5-hour-long coding interview course, you will learn about all essential data structures and how to use them. You will also learn about Big O notation, key metrics to measure algorithms performance, and how to compute Big O notation for any coding interview solution. 

The best thing about this course is that you will learn from a Senior Engineer who has managed teams of engineers and has been in these interviews on both sides of the table. Andrei's teaching skills and its awesome animation-based course lecture makes learning even easier. 

In short, one of the best coding interview courses to master algorithms and data structure. It can help you ace your coding interviews and land your dream job as you will learn tips to get more interviews, more job offers, and a higher salary. I highly recommend this course to anyone preparing for coding interviews.

You can also use my code FRIENDS10 to get a 10% discount on any subscription you choose. 

3. JavaScript Algorithms and Data Structures Masterclass

This is one of the best courses to learn Data Structures and Algorithms in JavaScript, and seriously, you won't find a better course at such a ridiculous price.

I bought this course for just $10 on Udemy's flash sales, which happens every month, and I am amazed by its quality. The reason I bought this course is because of Colt Steele, he is one the best instructor on Udemy and his classes are just awesome.

Having attended his course The Web Developer Bootcamp, I was sure of the quality, and when I see he has covered Data Structure and Algorithms, I couldn't resist buying this course.

As Colt mentioned, This course crams months of computer science and interview prep material into 20 hours of content, which has helped his bootcamp students ace interviews at big tech companies like Google, Tesla, Amazon, and Facebook.

The course not only covers basic data structures like an array, linked list, and binary tree but also includes "advanced topics" like Heaps, Graphs, and Dijkstra’s Shortest Path Algorithm.

You will not only learn about data structure but also about how to analyze your code’s time and space complexity using Big O notation and techniques to reduce them by making a space-time trade-off.

The course also covers the ins and outs of Recursion, a vital technique to solve many linked lists and binary tree-based questions. You will also learn techniques to solve difficult coding problems you might see the first time. In short, one of the best courses to learn data structure and algorithms in JavaScript.

4. Algorithms and Data Structures in Python

This is the best data structure and algorithm course I have come across for Python developers.

It covers both basic and advanced data structure like Arrays, Linked Lists, Trees, Hash Tables, Stacks, Queues, Heaps, Sort algorithms like QuickSort, MergeSort, and Insertion sort, and Search algorithms like linear and binary search.

The course also covers some of the advanced algorithms like shortest path algorithms, Dijkstra's algorithm, Bellman-Ford algorithm, Kruskal algorithm, spanning trees, etc.

On sorting algorithm, it covers basic ones like the bubble sort, selection sort, and insertion sort, along with quicksort and the merge sort. It also includes non-comparison-based sorting algorithms like Counting sort and Radix sort.

All the code examples and problems are implemented using Python programming language so that you don't have any difficulty in understanding how to apply them on your own.

5. Algorithms and Data Structures - Part 1 and 2

Being a Java developer, I am a little bit biased to include more data structure and algorithm courses using Java Programming language than any other language, and this is another awesome course to learn data structure and algorithms in Java. 

Another reason is that I have spent most of my team coding in Java, so I have just attended a lot more courses in Java than JavaScript or Python and that's why I share more DSA courses on Java than any other programming language. 

This one is another impressive course to learn data structure and algorithms which I have attended and found suitable. In this Pluralsight data structure and algorithm course, you will learn about the core data structures and algorithms used in everyday applications.

You will learn about the trade-offs involved with choosing each data structure, along with traversal, retrieval, and update algorithms. Btw, you would need a Pluralsight membership to join this course which costs around $299 per annum but also give access to more than 7000+ high-quality courses. 

This is part 1 of a two-part series of courses covering algorithms and data structures. In the second part of the course, you will learn linked lists, stacks, queues, binary trees, and hash tables. I suggest you go through both pieces to understand both basic and advanced data structures.

6. From 0 to 1: Data Structures & Algorithms in Java
