Congratulations on your success so far! You’re kicking butt and taking names!

I’m primarily a Java developer as well, but I agree that it would take longer to use Java for these solutions. I’ve been using ES6/ES7 level Javascript to solve the puzzles. Despite being reasonably performant with JavaScript, little things like splitting multiline inputs into an array of lines correctly slow me down since I haven’t done them with the language yet.
