TypeScript from Basic to Advanced

This repository provides a comprehensive guide to TypeScript, covering everything from the fundamentals to advanced concepts. Each chapter focuses on a key topic (from basic setup and types to generics, classes, interfaces, etc.) and includes an instructions.txt file with theory notes, practical examples, and interview-style questions. The content is carefully structured for beginners, intermediate developers, and students to learn and reinforce TypeScript skills.

Topics Covered

• Basic Concepts & Setup: Introduction to TypeScript, environment setup (Node.js, tsconfig), and fundamental types (number, string, boolean).
• Arrays & Configuration: Working with TypeScript arrays, and configuring the TypeScript compiler (tsconfig.json).
• Generics: Understanding generic types and how to use them for flexible, type-safe functions and classes.
• Readonly & Optional: Using readonly modifiers and optional properties in interfaces/types to create immutable and flexible data structures.
• Tuples: Learning about tuple types, how they differ from arrays, and advanced tuple usage.
• Type Aliases: Defining custom type aliases for cleaner code and reusability.
• any vs unknown: Exploring the differences between any and unknown types and best practices for type safety.
• Classes: Introduction to object-oriented programming in TypeScript, including classes, inheritance, and access modifiers.
• Interfaces: Defining object shapes, implementing interfaces in classes, and interface inheritance.
• Union & Intersection Types: Using union and intersection types to compose complex type definitions.

Each topic folder contains clear examples, code snippets, and an instructions.txt file that guides you through the concepts with explanations, practical exercises, and interview preparation questions.

Setup & Usage

1. Clone the repository:

   git clone https://github.com/Wcoder547/Your-Repo-Name.git

2. Install TypeScript (if needed): Ensure you have Node.js installed, then run:

   npm install -g typescript

3. Compile the code: Navigate to any chapter folder and compile the TypeScript file:

   tsc index.ts

   This will generate an index.js JavaScript file in the same folder.

4. Run the output: Execute the compiled code with Node.js:

   node index.js

5. Explore & Learn: Open the instructions.txt in each folder to read theory, follow along with the examples, and try the exercises.

Who Is This For?

• Beginners: New to TypeScript or coming from JavaScript and want a structured path to learn TypeScript basics.
• Intermediate Developers: Familiar with TypeScript basics and looking to solidify knowledge of advanced features and best practices.
• Students: Preparing for coding interviews or enhancing academic learning with real-world TypeScript examples.

Prerequisites: A basic understanding of JavaScript (ES6+) and Node.js will help you make the most of this content.
