Functional Programming Functions

This project is a collection of functional programming functions written in TypeScript. The functions are designed to be composable and reusable, allowing you to build complex data transformations and processing pipelines.

Installation

To use these functions in your project, you can install them via npm:

npm install funcode

Usage

To use a function, you can import it from the package:

import { pipe } from 'funcode';

const add = (b: number) => (a: number) => a + b;
const square = (n: number) => n * n;

const result = pipe(2, add(3), square); // 25

Functions

createPipe

Creates a new function that applies a series of operations to a value in sequence.

import { createPipe } from 'funcode';

const add = (b: number) => (a: number) => a + b;
const square = (n: number) => n * n;

const myPipe = createPipe(add(3), square);
const result = myPipe(2); // 25

pipe

Applies a series of operations to a value in sequence.

import { pipe } from 'funcode';

const add = (b: number) => (a: number) => a + b;
const square = (n: number) => n * n;

const result = pipe(2, add(3), square); // 25

tap

Executes a side effect and returns the original value, ideal for debugging.

import { tap } from 'funcode';
import { add, square } from './';

const log = (value: any) => console.log(value);

const result = pipe(2, tap(log), add(3), square); // 25

when

A collection of functions that receive a function and execute it if the value matches the condition.

import { eq, gt, gte, lt, lte } from 'funcode/when';

const result = pipe(2, eq(2, (val) => val * 2), gte(4, (val) => val * 2)); // 8
