This way, you transfer what you already know (problem-solving) but only change the syntax. Platforms like Hackerrank are also great to solve the same problem in different languages and learn from other people’s solutions. - Source: dev.to / about 1 year ago
Firstly, solve some common data structure problems with it. Implement some data structures like arrays, linked lists, stacks, queues, etc. You can check common problems on LeetCode, Hackerank or some other resources. - Source: dev.to / over 2 years ago

An effective way to improve your JavaScript skills is working through coding challenges and exercises. Sites like ReviewNPrep, FreeCodeCamp, and HackerRank have tons of challenges that allow you to practice JavaScript concepts by building mini-projects and solving problems. These hands-on challenges force you to apply what you learn. Source: almost 3 years ago
I'm 18M Indian. Growing up I've always been a daydreamer, if you may. Since 8th grade - I'm fascinated by programming. And I'm good at it too. But I'm not cocky too. I wouldn't say I'm at an advanced level, but I can most probably solve any problem - in time - with my skills. I also keep my skills brushed by solving problems on Hacker Rank (every day or alternate days) and try my best to contribute on... Source: almost 3 years ago
I would recommend that people stop taking this kind of bait, especially as an organization. Discord is free for now but that's bound to change and you can't have any expectation of privacy there. In my eyes they're practically the poster child for an organization who could (and arguably should) be running their own solution on their own servers. Perhaps self-hosted Revolt Chat [1] which I've been keeping an eye on... - Source: Hacker News / 12 months ago
I like Matrix but unfortunately it has major stability issues. The GrapheneOS project moved most of their chat over to Discord after their Matrix community got nuked twice. They still maintain a Matrix community which is bridged to their Discord instance, but most users are on the Discord side of the fence. IMHO, Revolt is a better FOSS Discord alternative: https://revolt.chat/. Relatively young project, but they... - Source: Hacker News / over 1 year ago
Really makes you wonder if/when Discord goes IPO, that Meta would buy a controlling stake in it? Fortunately there are open source alternatives even if they aren't as popular as Discord at the moment, such as Revolt Chat: https://revolt.chat/ I miss the days of self-hosted forums; sadly it seems that algorithms, and the need to satisfy the need for 'instant' connection/information are ruining forums for young... - Source: Hacker News / over 1 year ago
