TypeScript Unlocked: Write Safer, Smarter JavaScript

Solid understanding of JavaScript fundamentals
Basic familiarity with HTML and CSS
Experience with any front-end or back-end JavaScript framework is a plus

This course introduces participants to TypeScript, the typed superset of JavaScript that brings structure, scalability, and reliability to modern web development. Through hands-on exercises, learners will understand how TypeScript enhances JavaScript applications with static typing, interfaces, generics, and other advanced features that make code safer and easier to maintain.

• Introduction to TypeScript: why and when to use it
• Understanding transpilation and TypeScript configuration
• Basic types and type annotations
• Type inference and type checking
• Interfaces and type aliases
• Classes, inheritance, and specificities of TypeScript’s OOP model
• Enums and constants
• Functions: overloads, return types, and parameter typing
• Generics and reusable patterns
• Conditional types and utility types
• Advanced typing: keyof, typeof, and mapped types
• Built-in utility types (Record, Pick, Omit, etc.)
• Working with modules
• Integrating TypeScript into existing JavaScript projects
• Debugging and compiler options
• Best practices for large-scale TypeScript codebases

The course alternates between theory and guided coding exercises. Participants will progressively build and refactor a project using TypeScript features, gaining practical experience with typing strategies, debugging, and code design.
