Geeksforgeeks not a good place to get started with programming
My preferred way to pick up skills for a language is still the comment section of StackOverflow Specifically, people will have a highly upvoted response, but then comments saying stuff like "This wont work great in because of " or "If you need take a look at because " Deep diving down one of those rabbit holes pretty much is always one TIL after another and I come out feeling like I learned some cool new tricks of the trade.

February 21, 2021Is the GeeksforGeeks DSA (Algorithms & Data Structures) section still bad?
A lot of geeksforgeeks is really really bad - some articles are just plain wrong, some only have smaller mistakes - like using the wrong terms, or having code-examples that doesn't do what the text suggest - and some seem to be AI generated slop. Unfortunately you can't always see when something is wrong - a good article and a bad article often looks kind of similar, and there doesn't seem to be any quality control, so I recommend against using them completely.

r/learnprogramming on Reddit: Geeksforgeeks not a good place to get started with programming
February 21, 2021 -
I have seen many people recommending GeeksforGeeks to get started with programming.
But the truth is, many article is very poorly written, along with poor UI/UX design.
From what I have seen, Its just a place where code from different website and books are copied and compiled on a single website.
Let's just take example of method 4.
https://www.geeksforgeeks.org/check-whether-two-strings-are-anagram-of-each-other/
It's been a year since the method 4 has not been removed, this was one such code I found out today.
https://www.geeksforgeeks.org/length-of-longest-subarray-in-which-elements-greater-than-k-are-more-than-elements-not-greater-than-k/?ref=rp-Wrong approach
https://www.geeksforgeeks.org/longest-subarray-count-1s-one-count-0s/?ref=rp - Logically incorrect.
Many article with wrong time complexity, slow approach, poor explanation have just ruined the quality of content.
Would not recommend GeeksforGeeks.

The quality seems to vary a lot. Some of it is not very good at all.

r/learnprogramming on Reddit: Is the GeeksforGeeks DSA (Algorithms & Data Structures) section still bad?
May 25, 2025 -
four years ago a reddit post highlighted issues with the problem solutions on GeeksforGeeks and shared three links as examples however when I check those links now, I don't see any problems it seems geeksforgeeks has been updating these tutorials since 2024
despite this does learning from geeks4geeks worth? If not, could you recommend similar platforms which categorize algorithmic topics clearly provide complete tutorials for each problem allow testing code directly on the platform?
Thanks in advance!

My experience with GeeksForGeeks can be summarized as follows: Read tutorial. Half way through, think “wtf that’s not what I thought thing X was.” Spend an hour or so searching other sources to check my understanding. Realize tutorial is wrong. Close tab and swear not to visit them again. Repeat every few months.
