HOCs didn't die with hooks. React.memo, Redux connect, and half your favorite libraries still use them. Learn to write type-safe HOCs and when to reach for the pattern.

Conditional types and mapped types let you write types that compute — filtering keys, extracting nested types, and deriving new shapes from old ones without duplication.
