Function Composition via Pipe Combinators

Pipe is a functional programming pattern that composes multiple functions into a single transformation pipeline. It improves readability by allowing data to flow from left to right, avoiding deeply nested function calls and reducing imperative boilerplate.

snippet.js
javascript
const pipe = (...fns) => (initialValue) => 
  fns.reduce((acc, fn) => fn(acc), initialValue);
 
const normalize = s => s.trim().toLowerCase();
const slugify = s => s.replace(/\s+/g, '-');
const label = s => `id:${s}`;
 
const createSlug = pipe(normalize, slugify, label);
console.log(createSlug('  Expert JS Snippet  ')); // 'id:expert-js-snippet'

Breakdown

fns.reduce((acc, fn) => fn(acc), initialValue)

Sequentially applies each function in the array to the accumulated result.

const createSlug = pipe(...)

Creates a new reusable function by composing smaller, specialized functions.
