Greetings, Matthew. Pleased to see a like-minded programmer. I'm new as well.

I too focus on Javascript.. I'm still learning, but I do hope to eventually help develop blockchain solutions. 

While I'm currently using React as much as I can, it's mainly  because there's so much infrastructure has already been built with it, and to improve my Javascript skills. Hopefully by the end of this year, Vue will reign as king.
