We have collected here some useful links to help you find out if LeetCode is good.
Check the traffic stats of LeetCode on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of LeetCode on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of LeetCode's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of LeetCode on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.

You can specify the library you're using to get it better written, then I'd recommend reading the test and making sure all is accounted for. This way your next step will be to just write the function in a way it gives you the results you want and also passes your tests. If you are into leet code, this is pretty much the same you do when trying to make your function pass. - Source: dev.to / about 1 year ago

LeetCode remains one of the most prominent platforms in the realm of coding interviews and technical skills enhancement. Widely regarded as an ideal training ground for those gearing up for job interviews at top tech firms, it facilitates a rigorous regime for honing algorithmic and problem-solving acumen. The platform is especially favored for its extensive library of over 2,000 coding problems, ranging from easy to challenging levels, making it a comprehensive training palette for developers of varied skill levels.
Public Perception:
The consensus within the developer community is that LeetCode shines as a powerful resource for mastering data structures and algorithms, which are core components of many tech interviews. The platform's capability to replicate real-world interview scenarios through its curated problems and mock interviews is often highlighted as one of its significant advantages. Users praise its diverse and well-structured question bank that systematically prepares candidates for FAANG-level interviews, making it indispensable for many aspiring software engineers.
LeetCode is frequently mentioned alongside competitors such as HackerRank, CodeSignal, and Codewars, indicating its position in a vibrant ecosystem of coding practice platforms. While LeetCode boasts strengths, particularly in long-term algorithm practice and interview preparation, the landscape is competitive. Users looking for alternate experiences might turn to platforms like Codewars for gamified coding challenges or Hackerrank for language-specific tasks and company-sponsored competitions.
Critiques and Limitations:
While highly valued in the software engineering domain, LeetCode's scope is occasionally noted as limited concerning non-software development fields like data science. Critics argue that LeetCode is primarily tuned for coding interviews rather than analytical roles that require proficiency in SQL or Python for data analysis. Hence, professionals seeking preparation for data science roles may need to look elsewhere for tailored resources.
The premium model adopted by LeetCode also garners mixed feedback. While some users appreciate the added features and resources such as detailed solution discussions and community interaction that comes with a premium subscription, others express a preference for free resources that might not lock valuable educational content behind a paywall.
Community and Development:
A vibrant community, formed around shared experiences of tackling challenges and exchanging knowledge, bolsters the platform's reputation. This community aspect is crucial for many users, providing them with insights, alternate solutions, and moral support as they navigate through the often daunting labyrinth of competitive programming.
In essence, LeetCode has successfully carved out a niche for itself by consistently delivering value to those in pursuit of software engineering roles. The platformโs evolution continues to reflect its commitment to expanding and refining its offerings, readying developers worldwide for the intense scrutiny of technical interviews, while igniting debates on the best strategies for holistic programming education.
