Hello,
Currently, there is no way to check leetcode contest solutions for a specific programming language.
I always wanted to view JavaScript / Python solutions and I end up going through bunch of solutions in brute force manner. So I built this small plugin :-D
There's new section called "Language" being added in the ranking page

Check this out:

Installation (If you have tampermonkey):

How-to:
Limitations / Future enhancements:
This is just my way of contributing back to leetcode. Thank you for hosting awesome contests!
Thanks,
