Modern JavaScript, TypeScript & React

Master the complete modern web engineering stack in one cohesive, hands-on textbook.

Most developers learn JavaScript, TypeScript, and React in fragments-jumping into frameworks before understanding closures, the Event Loop, or static type narrowing, and struggling when real-world applications scale.

In Modern JavaScript, TypeScript & React, software architect and educator Oswald E. guides you step by step from your very first line of JavaScript to architecting full-stack, type-safe production systems. Updated for the modern 2026 ecosystem-including ECMAScript 2025/2026, TypeScript 5.8+, React 19.2, the React Compiler, Vite 6, Tailwind CSS v4, TanStack Query v5, TanStack Router, Zustand v5, React Hook Form + Zod, Next.js App Router, Vitest, and Playwright-this 800+ page textbook leaves zero gaps in your engineering foundation.

Inside this comprehensive 36-chapter curriculum, you will:

• Master Core & Advanced JavaScript: Understand V8 execution contexts, closures, this binding, prototypal inheritance, async/await, the Event Loop, memory management, functional pipelines, Generators, and Proxy metaprogramming.
• Think in Type-Level TypeScript: Progress from "strict": true compiler setup and interfaces to generics, custom type predicates, discriminated unions with exhaustive never checks, mapped types, conditional infer types, and template literal types.
• Build Production React 19 & Next.js Applications: Move cleanly from declarative React fundamentals in JavaScript to strict .tsx components, custom hooks, URL state routing, TanStack Query server-state caching, React Server Components (RSC), and Server Actions.
• Learn by Building 17 Full Capstone Projects: Reinforce every chapter with line-by-line code walkthroughs, refactoring workshops, 72 hands-on coding assignments with worked solutions, and 180+ self-assessment quiz questions with complete explanations.

Whether you are a self-taught developer, a computer science student, or a working engineer upgrading to the modern React 19 and TypeScript stack, grab your copy today and start building resilient, production-grade web applications.
