5 Best Online Courses for Data Structures and Algorithms

Data Structures & Algorithms

Here are some best online courses for Data Structures and Algorithms for interview prep and improving your coding skills.

If you’re new to programming, you can start with Python.

A good knowledge of data structures and algorithm not only helps you to write efficient code, it improves overall logic building skills and helps to discriminate between a good code and bad code. Even coding interviews are based on DSA.

To learn DSA one need to have command on at least one programming language, like C++, JavaScript, Python Java etc. Know – How long does it take to learn Coding?

If you want to learn DSA and want to choose some good courses for your study then you can choose any of the courses given below.

After researching and trying many courses, I am sharing some best Data Structures and Algorithm courses for you by considering effectiveness, time, affordability, rating and flexibility.

JavaScript Algorithms And Data Structures Masterclass

Platform: Udemy

Instructor: Colt Steele

It is an interactive course with JavaScript for data structures and algorithms. The course comes with video lectures, coding problems and visual examples. 

Colt prepares you with tips and tricks to help you to choose the best approach to solve problems by using animation and explanatory diagrams. 

This course is for anyone who wants to learn data structure and algorithms for interview preparation and improve problem-solving skills.


Data Structures and algorithms helps programmers to improve problem solving skills with some techniques to manage data efficiently and right tools to approach the solution. Also it has much role in technical interview as interviewers can evaluate candidates knowledge of programming majorly using DSA. A software developers need to be involved in coding, design, maintenance and optimization of software.

Frequently Asked Questions(FAQs)

What is the fastest way to learn data structures and algorithms?

In sort: First learn one language and be comfortable with the syntax and programming, you can start with any of C++, Python, JavaScript etc, pick good course or book to learn DSA, practice daily problems on any site. Gradually you can able to implement algorithm and analyze codes and write good codes.

How long will it take to learn data structures and algorithms?

Usually 6 to 8 weeks but you need sufficient practice, as you proceed on learning programming you can improve yourself by making your hands dirty with codes.

Is Python good for data structures?

See, Data Structures are just theories that you can apply on any programming language, it gives you techniques to organize data in memory for fast retrieval. You can learn it with Python but Python have easy syntax and some abstractions also pointers are abstracted in Python. On the other hand C++, Java etc makes you to apply your own data structures with some complexity (but wort it) from scratch with no hiding at all.
