Overview

This PR addresses issue #X by adding TypeScript type alias files to complement the existing C# type aliases in the repository. The implementation provides multilingual type aliases that allow developers to write TypeScript code using their native language.

What's New

TypeScript Type Aliases

Created a new TypeScriptAliases/ directory containing type alias files in three languages:

  • 🇬🇧 English (english-type-aliases.ts) - 88 type aliases
  • 🇪🇸 Spanish (español-alias-tipos.ts) - 90 type aliases
  • 🇹🇼 Traditional Chinese (中文類型別名.ts) - 90 type aliases

Comprehensive Type Coverage

Each language file provides type aliases for:

  • Basic types: Text/string, Integer/number, Boolean, Date, Byte arrays
  • Function types: Callbacks, Predicates, Mappers, Comparators, Async operations
  • Collection types: Lists/arrays, Dictionaries/Records, Maps, Sets, Tuples
  • Utility types: Optional, Nullable, Maybe, NonNullable
  • DOM types: HTML elements, Event listeners, Mouse/Keyboard events
  • HTTP/Network types: Headers, JSON objects and values
  • Time types: Milliseconds, Seconds, Minutes, Hours, Timestamps
  • File types: File names, paths, extensions, MIME types
  • ID types: Unique identifiers, Numeric IDs, UUIDs
  • Result types: Result and Either types for error handling
  • Advanced types: Constructors, Type guards, Async functions

Usage Examples

English

import { Text, Integer, TrueOrFalse, List } from './english-type-aliases';

const name: Text = "John Doe";
const age: Integer = 30;
const hobbies: List<Text> = ["reading", "coding"];

Spanish (Español)

import { Texto, Entero, Booleano, Lista } from './español-alias-tipos';

const nombre: Texto = "Juan Pérez";
const edad: Entero = 30;
const pasatiempos: Lista<Texto> = ["leer", "programar"];

Traditional Chinese (繁體中文)

import { 文本, 整數, 布林值, 列表 } from './中文類型別名';

const 姓名: 文本 = "張三";
const 年齡: 整數 = 30;
const 愛好: 列表<文本> = ["閱讀", "編程"];

Project Configuration

  • package.json: TypeScript dependency and build scripts
  • tsconfig.json: ES2020 target with strict type checking enabled
  • Example files: Practical demonstrations for each language
  • Documentation: Comprehensive README with usage instructions

Documentation Updates

  • Updated main README to reflect both C# and TypeScript support
  • Added multilingual examples for both languages
  • Created TypeScript-specific README with detailed usage guide
  • Updated .gitignore to exclude build artifacts (dist/, package-lock.json)

Testing

✅ All TypeScript files compile successfully with zero errors
✅ Existing C# solution continues to build without issues
✅ Code review passed
✅ Security scan completed with 0 vulnerabilities

Educational Value

This implementation maintains the educational philosophy of the repository by enabling developers to:

  • Learn TypeScript type systems using familiar terminology
  • Write code in their native language
  • Understand type relationships through meaningful names
  • Transition between languages more easily

The TypeScript type aliases follow the same pattern as the existing C# aliases, providing consistency across the repository and making it a comprehensive multilingual type alias resource for both .NET and JavaScript/TypeScript developers.
