What Does "use client" Do?

This article provides a deep dive into React's 'use client' and 'use server' directives. It argues that these concepts are foundational programming paradigms, comparing them to structured programming and async/await. The author explains how 'use client' acts as a typed script tag and 'use server' as a typed fetch, allowing developers to model a client/server application as a single program across the network boundary, enabling seamless composition.
