What does npm run build do in React?

Optimizes code—minifies JS/CSS, removes dev code, bundles assets into /build for static serving. No runtime needed.

How to run Dockerized React on localhost?

`docker run -p 8080:80 your-image`. Visit http://localhost:8080. Map avoids port conflicts.

Frontend: static nginx (23MB, port 80). Backend: dynamic Node (135MB+, custom port). Build once/serve forever vs constant runtime.
