TypeScript Decorators

Overview

This repository contains a TypeScript laboratory exercise completed during my undergraduate studies. The purpose of this exercise was to understand and implement TypeScript decorators, classes, and object-oriented programming concepts.

Learning Objectives

• Understand TypeScript decorators
• Explore class-based programming
• Learn TypeScript compilation and configuration
• Practice TypeScript syntax and features
• Gain experience with JavaScript and TypeScript interoperability

Technologies Used

• TypeScript
• JavaScript
• Node.js

Project Files

• index.ts – Main TypeScript implementation
• class.ts – Class and decorator examples
• index.js – Compiled JavaScript output
• class.js – Compiled JavaScript output
• tsconfig.json – TypeScript compiler configuration
• package.json – Project dependencies and scripts

Concepts Covered

Decorators

This project demonstrates the use of TypeScript decorators for:

• Class decoration
• Metadata enhancement
• Code reusability
• Custom behavior implementation

Object-Oriented Programming

• Classes
• Objects
• Methods
• Constructors
• Encapsulation

How to Run

1. Install dependencies

npm install

2. Compile TypeScript

tsc

3. Run the generated JavaScript

node index.js

Academic Purpose

This repository was created as part of a college laboratory exercise to gain practical experience with TypeScript and decorator-based programming concepts.

Learning Outcome

Through this exercise, I developed a foundational understanding of:

• TypeScript development
• Decorator patterns
• TypeScript compiler configuration
• Object-oriented programming principles
