• Understanding never and void

2. Working with Objects & Arrays

• Defining types for objects
• Type Aliases for reusable type definitions
• Using readonly and ? (optional properties)
• Adding type safety for arrays
• Union Types
• Tuples
• Enums

3. Advanced Type Features

• Interfaces and their special use cases
• Difference between Type and Interface
• Generics for reusable and flexible code
• Type Narrowing
• Discriminated Unions
• Type Predicates

4. Classes & Object-Oriented Features

• Creating classes in TypeScript
• public vs private vs protected properties
• Getters & Setters
• Abstract Classes and when to use them

5. Project & Config

• Understanding and configuring tsconfig.json
• Why interfaces are important in real-world projects
• Special cases where interfaces shine

🛠 How I Learned

I practiced each concept by:

1. Writing small, focused examples
2. Integrating them into larger code snippets
3. Using tsc compiler for type checking
4. Reading the TypeScript documentation & real-world backend use cases

📅 Next Steps

• Mastering TypeScript with Prisma for backend development
• Applying TypeScript best practices in full-stack projects
• Learning decorators and advanced type inference

📌 Why This Matters

TypeScript isn't just for type safety — it helps write clean, maintainable, and bug-resistant code. As a backend developer, mastering TypeScript ensures stronger contracts between services, safer database interactions, and better collaboration in large teams.
