Answer
Docker eliminates environment mismatch problems by packaging apps with all dependencies into portable containers that behave consistently across machines.
Quick Answer
Before Docker, "works on my machine" was a real problem — different OS, different libraries, different configs on dev vs prod. Docker packages your app and all its dependencies into one container that runs identically everywhere. No more environment drift, no more manual setup, no more surprise failures at deployment.
