TypeScript Unlocked: Write Safer, Smarter JavaScript

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 

• Understand the role of TypeScript in modern web development. 
• Write safer and more predictable code using static typing and inference. 
• Master advanced typing concepts (generics, conditional types, utility types). 
• Confidently use TypeScript with frameworks like Angular, React, or Node.js. 
• Set up and maintain a professional TypeScript development environment. 

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.
