If someone need my suggestion, here is what you do - try doing different sort of questions (multiple topics too) on leetcode from different topics may be just 20-30 in language you want to learn.

Its different way but you will learn a lot of new libraries, ways to mutate objects, lists, all sort of data structures and new things really really fast.

Leetcode is leetcode. It's its own skillset within software engineering, one you often need to get a job, but it bears pretty little resemblance to any of the skills you need to deliver working, functional software that solves a user's problem. Practicing it will help you get better at it, which may help you land a job where you can practice all the other skills, but don't confuse leetcode with proficiency in software development.

Among other differences, leetcode teaches you little about reading large unfamiliar codebases; debugging; organizing large software-engineering projects; working in teams; teasing out actual requirements; making incremental progress; real-world performance (and the tools you need to identify bottlenecks); and most of the libraries and frameworks that are common industry knowledge.

I have a feeling that most of these skills don't change all that much between languages

Knowing important utility libraries and toolchain of the language is important and it differs significantly between languages.

Doing Leetcode doesn't even teach how to build a 10000 LoC project.

I’ve tried a lot of those, even contributed to exercism. I think it has it’s uses, but you can only extract value from those exercises once you know enough about a language.

For me those exercises are more about developing muscle memory than really learning a language.

OPs idea is good, but I think fails in the same way. I don’t think you’ll get much value out of reading PRs until you have certain familiarity. No amount of PRs will teach you what a monad is, you need to dive deep and conceptually understand the model(at least IMO).

I've only done a few leet code questions but only in languages that I'm comfortable with. Even then, I've had similar experiences to the author mentions where I've gotten different perspective on how to approach certain problems.
