Why DSA Still Matters
Here’s the truth: writing code is one thing, writing efficient code is another. Data structures and algorithms (DSA) are what separate code that works from code that scales.
But let’s be real—learning them can feel overwhelming. Where do you start? Do you grind LeetCode? Read textbooks? Watch tutorials until your eyes blur?
The better question is: What’s the best platform to learn data structures and algorithms?
I’ve tested most of them. Here’s the list.
The List: Best Platforms to Learn Data Structures and Algorithms
1. Educative.io – My Top Pick
If you want the short answer, the best platform to learn data structures and algorithms is Educative.io.
Why?
- Interactive, no-video format.
- Courses like Grokking the Coding Interview are legendary.
- Explains both the how and the why.
- One sub = DSA + system design + language courses.
👉 Honestly, this was the only platform that helped me internalize patterns instead of just memorizing solutions.
2. LeetCode
Great for practice, overwhelming for beginners.
Pros: massive problem bank, real interview questions.
Cons: no structure, no explanations.
3. HackerRank
Similar to LeetCode, but with cleaner UI.
Pros: free, instant feedback.
Cons: not great for learning fundamentals.
4. Coursera
University-style courses.
Pros: structured, academic, certs.
Cons: video-heavy, not interactive.
5. Udemy
Cheap courses, lifetime access.
Pros: affordable, wide variety.
Cons: quality varies, some outdated.
6. Brilliant.org
Puzzle-style learning.
Pros: interactive, visual, fun.
Cons: not focused on interviews.
7. Codeforces
For hardcore competitive programmers.
Pros: **contests, global community.
**Cons: steep learning curve.
8. MIT OpenCourseWare
Free MIT lectures.
Pros: **deep theory.
**Cons: heavy, no practice.
9. GeeksforGeeks
The encyclopedia of DSA.
Pros: tons of articles + tutorials.
Cons: text-heavy, inconsistent.
10. InterviewBit
Interview-focused platform.
Pros: structured interview prep.
Cons: limited scope beyond interviews.
So… What’s the Best Platform?
- Free → YouTube/GeeksforGeeks.
- Interview grind → LeetCode/InterviewBit.
- Academic → Coursera/MIT.
- Job-ready + structured → Educative.io.
That’s why my top recommendation for the best platform to learn data structures and algorithms is Educative.io.
