TypeScript: JavaScript with Superpowers

TypeScript is a superset of JavaScript that adds static typing. Developed by Microsoft, it compiles to plain JavaScript and runs anywhere JavaScript runs. TypeScript catches errors at compile time, improves code documentation, and enables better IDE support — making it ideal for large, complex projects.

• Type Safety: Catch errors before they reach production
• Enterprise Adoption: Used by Google, Microsoft, Airbnb, Stripe
• Better Developer Experience: Superior autocomplete and refactoring
• Growing Demand: Fastest-growing language in job listings
• Framework Standard: Angular uses TypeScript, React/Vue support it

• JavaScript Developers: Level up with type safety
• Angular Developers: TypeScript is mandatory for Angular
• Backend Developers: Build type-safe Node.js applications
• Team Leads: Improve code quality and maintainability

• TypeScript types and interfaces
• Generics and advanced types
• Decorators and metadata
• Module systems and configuration
• TypeScript with React
• TypeScript with Node.js
• tsconfig.json configuration
• Migration from JavaScript
