💻 Which Data Structures and Algorithms Course Provider is best for me?

Udemy and Eduonix are best for practical, low cost and high quality Data Structures and Algorithms courses. Coursera, Udacity and EdX are the best providers for a Data Structures and Algorithms certificate, as many come from top Ivy League Universities. YouTube is best for free Data Structures and Algorithms crash courses. PluralSight, SkillShare and LinkedIn are the best monthly subscription platforms if you want to take multiple Data Structures and Algorithms courses. Independent Providers for Data Structures and Algorithms courses & certificates are generally hit or miss.

📃 Is a Data Structures and Algorithms Certificate worth it?

Yes and No. Certified Data Structures and Algorithms developers on average make more money . Having a Data Structures and Algorithms certificate greatly increases the chance of landing an interview and can open otherwise closed doors. Coursera, Udacity and EdX offer excellent certificate options for impressing your future employers. Eduonix, Udemy and several other providers offer certificates, but they aren't as reputable. If you have a Computer Science Degree, certificates are not as important. Still, many employers won't care about certificates, but rather your interview skills, experience and/or skills assessment.

JavaScript Algorithms and Data Structures Masterclass (2026)

4.7

(31,271 reviews)

byColt Steele

Colt Steele's 22-hour JavaScript run through Big O, sorting, linked lists, trees, heaps, graphs and dynamic programming, with 81 coding exercises and a 4.7 from 31,000 reviews.

Best for: Working JavaScript developers who skipped computer science and have a technical interview coming up.

Pros

Cons

- Big O explained slowly with animations; one reviewer says it made the topic far less intimidating
- 81 coding exercises and 87 quizzes, with a chance to try every problem before the solution video
- Goes past the basics into heaps, graphs, Dijkstra and dynamic programming
- Refreshed in January 2026, carries Udemy's Bestseller badge and holds a 4.7 across 31,000 reviews
- Few LeetCode-style practice problems; it teaches structures, not interview grinding
- Budget far more than the 22 video hours; one reviewer logged 88 hours to finish
- JavaScript only, so it is less useful if you interview in another language

Data Structures and Algorithms: Deep Dive Using Java (2025)

4.5

(22,813 reviews)

byTim Buchalka

A 16 hour Java course that builds every classic data structure and sort algorithm by hand, from Tim Buchalka's academy, with over 22,000 reviews and a Bestseller badge.

Best for: Java developers who want to build lists, hash tables, trees and heaps themselves and understand what the JDK collections do inside.

2322387

Pros

Cons

- Each structure is explained with visuals first, then coded live, and reviewers say the pace is easy to follow.
- Spends real time on what the JDK already provides, so students learn when not to write their own.
- About 87 percent of 22,811 ratings are four or five stars, with under 3 percent at one or two.
- Full source code is included, and one reviewer ported the whole course to C# as an exercise.
- No graphs, tries, dynamic programming or greedy algorithms, which two reviewers asked for.
- Sorting takes 27 lectures and over four hours, and one reviewer found some sections ran long.
- Java version and Ubuntu install steps still feel dated to reviewers, despite an April 2025 update.

- A couple of quizzes keep it active; students say the small modules are easy to digest
- Almost no data structures: trees, graphs, hashing and maps are missing despite the title
- Last updated in 2018 and reviewers report forum questions go unanswered
- Later lectures stop giving worked code and tell students to figure it out alone
