What tech stack are you most comfortable with?

The industry changes pretty quickly but I can't think of anything too significant that's changed in the past four years. Also once you've learned enough tech it's not too hard to pick up something new quickly.

I knew basically no React when I was hired at my current job, I only knew Angular, and while they hired me for a client that wanted Angular, that fell through and they put me on a React team and I picked it up well enough to contribute more than bug fixes after like, two weeks, and now 3 years later I'm waaaay more comfortable with React than I ever was with Angular.
