Introduction to TypeScript: Enhancing JavaScript Development

This course introduces you to TypeScript, a superset of JavaScript that adds optional static typing and other features to improve your development experience.

Course Objectives:

• Understand the core concepts of TypeScript, including its relationship with JavaScript.
• Utilize fundamental TypeScript syntax to define variables, functions, and data structures with explicit types.
• Leverage the type system for improved code maintainability, error detection, and refactoring.
• Explore advanced TypeScript features like interfaces, generics, and decorators to enhance your code design and reusability.

Course Structure:

Module 1: Introduction to TypeScript

• What is TypeScript?
  • Superset of JavaScript
  • Benefits of static typing
  • Applications of TypeScript
• Getting Started with TypeScript
  • Setting up the development environment (TypeScript compiler, code editor)
  • Creating and compiling basic TypeScript code

Module 2: Fundamental Types and Operators

• Understanding Basic Types:
  • string, number, boolean, any
  • Type annotations and inference
• Working with Arrays and Tuples:
  • Defining and manipulating typed arrays
  • Utilizing tuples for fixed-length data structures
• Exploring Operators:
  • Arithmetic, comparison, logical, assignment operators
  • Type compatibility and type conversions

Module 3: Functions and Control Flow

• Defining Functions with Types:
  • Function parameters and return types
  • Arrow functions in TypeScript
• Control Flow Statements:
  • if, else, switch statements with type considerations
  • for, while, do-while loops with type annotations
• Error Handling:
  • try...catch blocks for handling runtime errors
  • Throwing and catching custom errors with types

Module 4: Interfaces and Classes

• Defining Interfaces:
  • Specifying contracts for object structures
  • Extending interfaces for code reusability
• Creating Classes:
  • Defining object blueprints with properties and methods
  • Access modifiers (public, private, protected)
  • Inheritance and polymorphism in TypeScript

Module 5: Generics and Advanced Features

• Introducing Generics:
  • Creating reusable components with type parameters
  • Working with generic functions and classes
• Exploring Modules and Namespaces:
  • Organizing code into logical modules
  • Managing naming conflicts with namespaces
• Decorators (Optional):
  • Adding metadata and modifying class behavior

Module 6: Testing and Debugging with TypeScript

• Unit Testing with TypeScript:
  • Setting up a testing framework (e.g., Jest)
  • Writing unit tests for your TypeScript code
• Debugging Techniques:
  • Utilizing browser developer tools and TypeScript compiler errors
  • Best practices for debugging and troubleshooting TypeScript code

Welcome to the world of TypeScript! This course will guide you through the journey of enhancing your JavaScript development skills with the power of static typing and modern features.
