Kickstart your journey into JavaScript's object-oriented world with this hands-on guide. You'll learn to think in objects, encapsulate state, and assemble code into clear, maintainable modules building the confidence to create real-world applications from day one. What You'll Learn
- Master the prototype chain and ES6 class syntax for flexible inheritance
- Encapsulate data with private fields, getters/setters, and module scopes
- Model "is-a" relationships via class hierarchies and "has-a" via composition
- Apply core design patterns. Factory, Singleton, Observer, Command, Strategy, State
- Share behavior with mixins, decorators, and context-based factories
- Structure modular code with IIFEs, CommonJS, ES modules, and UMD wrappers
- Bundle and optimize your code using Webpack, Rollup, tree-shaking & code-splitting
- Transpile modern syntax with Babel and TypeScript for broad browser support
- Enforce quality with Jest testing, ESLint linting, and living documentation
Hands-On Projects
- Build an EventBus-driven Task Scheduler using Command and Observer
- Implement a PaymentProcessor with injectable CreditCard, PayPal & Crypto strategies
- Package your modules into ES and CJS bundles, then configure Rollup for tree-shaking
- Create a Plugin Framework utilizing abstract handlers and registry metaclasses
- Optimize a particle simulation with the Flyweight pattern for massive scale
- Set up CI pipelines running lint, tests, coverage, and doc generation automatically
Who This Book Is For
- JavaScript developers moving from ad-hoc scripts to structured applications
- Engineers seeking a deep understanding of prototypes, classes, and patterns
- Architects and team leads designing scalable, maintainable codebases
- Students and self-learners wanting practical, project-driven OOP tutorials
Take the first step toward mastering robust, scalable JavaScript. Design systems that adapt, modules that interoperate, and applications that endure.
