Show HN: I made an extension to discover useful programming concepts

https://chromewebstore.google.com/detail/knew-tab/kgmoginkclgkoaieckmhgjmajdpjdmfa
1•sahp•22h ago
I wanted to showcase Knew Tab; a chrome extension I have been working on for a couple of weeks now. The idea is to introduce any beginner or intermediate programmer to concepts that might be useful in their workflow. Currently, it only supports Python but i'm working on adding support for almost any language. Personally, for a long time I did not know the existence of `collections.Counter` and how useful it can be, which is where the idea of Knew Tab came from. There are some rough edges and I would appreciate your feedback. As of now I have thought of the following changes in the next release:

- Support for more languages - Some way to save or export snippets that you like - Better styling for readability
