Some of the main advantages of Javascript are its community and ecosystem. The ecosystem is huge and it is very easy to get lost, literally. I have bookmarked over time a ton of Javascript resources. Here I put a list with my favourite Javascript Github repositories, which does not include frameworks (Angular, React & Co are most likely known by everyone).
