I recently finished my react personal website. It's built using react and It's being client-side rendered.

"SSR vs CSR" is kind of a new topic for me and I am currently (we can say) researching it.

There are tons of content on the subject out there. I have been reading those. But I didn't manage to find the answer to this question.

• When was CSR first introduced?
• Which framework supported CSR first?

I am also wondering if CSR was out there before ReactJS.

Can someone help answer those questions?
