  2. Practice type inference with example scenarios.

Day 3: Arrays and Tuples

  • TypeScript arrays and their type annotations
  • Introduction to tuples: defining and using them

Tasks:

  1. Create an array of strings and calculate its length.
  2. Define a tuple for a user’s ID and name.

Day 4: Object Types

  • Defining objects with TypeScript
  • Optional and readonly properties
  • Nested object types

Tasks:

  1. Define a Person object with properties like name, age, and isStudent.
  2. Create a nested object structure for a Book with title, author, and details.

Day 5: TypeScript Functions

  • Type annotations for function arguments and return types
  • Optional and default parameters
  • Function overloads

Tasks:

  1. Write a function to calculate the area of a rectangle.
  2. Add optional parameters to your function for units like “cm” or “inches”.

Day 6: Union and Literal Types

  • Understanding union types
  • Working with literal types and discriminated unions

Tasks:

  1. Write a function that accepts either a number or a string.
  2. Create a union type for shapes like circle and rectangle.

Day 7: Review and Quiz

  • Revise all topics from Week 1.
  • Take a beginner-level TypeScript quiz.

Week 2: Intermediate TypeScript Concepts

Goal: Dive deeper into TypeScript and handle real-world scenarios.

Day 8: Enums

  • Numeric and string enums
  • Using enums in your projects

Tasks:

  1. Create an enum for user roles like Admin, Editor, and Viewer.
  2. Write a function to return the role name based on the enum value.

Day 9: Interfaces and Type Aliases

  • Defining interfaces
  • Using type aliases
  • Extending interfaces

Tasks:

  1. Define an interface for a car with properties like make, model, and year.
  2. Use a type alias for a union of shapes (Circle | Rectangle).

Day 10: Advanced Functions

  • Function types and callbacks
  • Using this in functions

Tasks:

  1. Write a callback function to process an array of numbers.
  2. Create a function type for a mathematical operation.

Day 11: TypeScript Classes

  • Classes and constructors
  • Access modifiers (public, private, protected)
  • Inheritance

Tasks:

  1. Create a Person class with properties and a method to introduce themselves.
  2. Extend the Person class to create an Employee class.

Day 12: Generics

  • Generic functions
  • Generic classes
  • Constraints with generics

Tasks:

  1. Write a generic function to reverse an array of any type.
  2. Create a generic class for a key-value pair.

Day 13: Utility Types

  • Exploring Partial, Readonly, Pick, and Omit
  • Practical use cases of utility types

Tasks:

  1. Use Partial to create a mutable version of a Person interface.
  2. Create a readonly version of an object using Readonly.

Day 14: Review and Quiz

  • Revise all topics from Week 2.
  • Take an intermediate-level TypeScript quiz.

Week 3: Advanced TypeScript Concepts

Goal: Master advanced features and TypeScript-specific tools.

Day 15: Keyof and Typeof

  • Using the keyof operator
  • Type queries with typeof

Tasks:

  1. Create a utility function using keyof to list object keys.
  2. Use typeof to infer the type of a variable.

Day 16: Advanced Types

  • Intersection types
  • Conditional types
  • Mapped types

Tasks:

  1. Write an intersection type for combining multiple interfaces.
  2. Create a mapped type to make all properties optional.

Day 17: Modules and Namespaces

  • Importing and exporting modules
  • Working with namespaces

Tasks:

  1. Split a project into multiple files and use modules.
  2. Use namespaces to organize code for a library.

Day 18: Decorators

  • Experimental decorators in TypeScript
  • Class and method decorators

Tasks:

  1. Create a class decorator to log the instantiation of a class.
  2. Write a method decorator to log the execution time of a function.

Day 19: TypeScript in Frontend Frameworks
