Learn TypeScript as a programming language first, so you can later apply it easily in automation.

🧩 Module 1: Basics (Foundation)

Lessons:

1. What is TypeScript (simple idea: JS + types)
2. Setting up TypeScript (run first file)
3. Variables (let, const)
4. Basic Types (string, number, boolean)
5. Type Inference (auto type detection)
6. any vs unknown (important difference)

🧩 Module 2: Working with Data

Lessons:

1. Arrays (list of values)
2. Tuples (fixed structure arrays)
3. Objects (key-value data)
4. Nested Objects
5. Optional properties
6. Readonly properties

🧩 Module 3: Functions (Very Important)

Lessons:

1. Function basics
2. Parameters and return types
3. Optional parameters
4. Default parameters
5. Arrow functions
6. Function types

🧩 Module 4: Control Flow (Decision Making)

Lessons:

1. if / else
2. switch
3. for loop
4. while loop
5. for...of (clean loop for arrays)
6. break and continue

🧩 Module 5: Objects & Reusability

Lessons:

1. Creating reusable object shapes
2. Interfaces (define structure)
3. Type aliases
4. Difference: Interface vs Type (simple rules)
5. Extending objects
6. Combining types

🧩 Module 6: Error Handling

Lessons:

1. What is an error
2. try / catch
3. throw custom errors
4. Safe coding patterns

🧩 Module 7: Async Basics (Must Know)

Lessons:

1. What is async code
2. Promise (simple idea)
3. async / await
4. Handling errors in async code

🧩 Module 8: Modules (Code Organization)

Lessons:

1. Why split code
2. export
3. import
4. Default vs named export

🧩 Module 9: Useful TypeScript Features

Lessons:

1. Union types (multiple possible types)
2. Literal types (fixed values)
3. Type narrowing (smart checks)
4. Optional chaining (safe access)
5. Null & undefined handling

🧩 Module 10: Clean Code Basics

Lessons:

1. Writing readable code
2. Naming variables clearly
3. Avoiding duplication
4. Small functions
5. Basic debugging

💡 What You Will Achieve

• Think like a programmer (not just tester)
• Write clean and predictable code
• Understand logic behind automation tools
