TypeScript Functional Programming Library - V2 (In Development)

🚧 This project is currently being rewritten from scratch for better performance and maintainability.

The previous implementation has been moved to the deprecated/ folder.

Current Status

Currently implementing core functions one by one with:

• Modern TypeScript practices
• Optimized performance
• Comprehensive testing
• Clean, maintainable code

Currently Available Functions

Array Functions

compact<T>(array: (T | null | undefined | false | 0 | "")[]): T[]

Creates an array with all falsy values removed.

import { compact } from 'typescript-functional-programming';

compact([0, 1, false, 2, '', 3, null, undefined, NaN, 4])
// => [1, 2, 3, 4]

Development Status

• ✅ Project structure setup
• ✅ TypeScript configuration
• ✅ Jest testing setup
• ✅ compact function implemented
• 🚧 More functions coming soon...
