Course Description
There's a gap between "React developer" and "React architect." This course bridges it. Nina Park contributed to the React core library at Vercel and has reviewed hundreds of production codebases — she knows exactly where most teams make the decisions that hurt them at scale.
You'll learn the patterns that make React applications maintainable as they grow: proper component composition, how to avoid prop drilling without context abuse, when to use server components versus client components in Next.js 14, and how TypeScript's type system can enforce architectural boundaries.
