This example demonstrates the functional programming concepts of `map`, `reduce`, and `pipe` in under three minutes using JavaScript. The code defines custom `reduce` and `map` functions, where `map` is built on top of `reduce` to transform array elements, and a `pipe` function that chains multiple functions together by sequentially passing an input through each one. The implementation uses iterable `for...of` loops and arrow functions, showing how these higher-order utilities operate on arrays and function compositions without relying on external libraries.

simple example of using a pipe function to reduce

This example demonstrates a JavaScript pipe function that composes multiple transformation functions into a single callable pipeline. The code defines a `Pipe` utility using the `reduce` method, chaining operations such as `double`, `triple`, and `quadruple` on a numeric input. The pipeline applies each function sequentially, ultimately producing the output `240` from the initial value `10` through the composed `path`. This showcases functional composition without external libraries, relying on core JavaScript array and function behaviors to illustrate a concise data-flow pattern.

A set of pure and immutable ES2015 functions aimed to make functional JavaScript more idiomatic.

This example presents a collection of pure, immutable ES2015 utility functions for idiomatic functional JavaScript. It includes array operations such as `combine`, `compact`, `difference`, and `intersection`, object helpers like `merge` and `toMap`, math functions (`min`, `max`, `sum`, `product`), and function decorators including `curry`, `once`, `maybe`, and `pipeline`. The code relies on native JavaScript features like `Array.prototype.includes`, `Set`, `Map`, `Object.assign`, and spread syntax. No external libraries or data sources are used; the gist demonstrates standalone, reusable functional patterns.

Gist 7d6a7404e99051bb7d2f36c61f0113ae

This example demonstrates functional programming techniques in JavaScript, including currying, composition, and generator functions. It shows how currying enables partial application, as seen with the `sum` function and reusable helpers like `getName` and `mapUserNames`. The code uses `compose` with `reduceRight` to chain array transformations, filtering user names by length. It also illustrates generator behavior with `next(true)` to control iteration completion. The data is a hardcoded array of user objects, and output is logged to the console via `console.log`.

Arrays

This example showcases JavaScript array manipulation techniques, including `forEach`, `filter`, `sort`, and `reduce`. The code logs a computed sum from a hardcoded array `[1, 3, 5, 10, 30]` using the `reduce` method, while commented-out lines demonstrate additional array operations. It renders no visual output; instead, it serves as a minimal HTML page with embedded JavaScript, illustrating functional programming concepts for educational purposes. The example relies solely on native JavaScript APIs without external libraries or data sources.

accumulator

This example demonstrates the array methods `reduce` and `map` in JavaScript, showing how to transform an array of key-value pair objects into a single object and how to map numbers to new objects with calculated properties. The code defines sample data and logs the results to the browser console, while the page displays a placeholder title with CSS styling. It uses plain JavaScript ES6 syntax, with no D3 or React logic present despite the framework metadata, and the HTML references an unmounted D3 script tag.

arrays

This example demonstrates fundamental JavaScript array operations through console logging, including iteration, filtering, sorting, mapping, and reducing. It shows a custom `range` function, a sorting comparator for numbers, and how to build objects from array entries using `reduce`. The code imports `ascending` and `descending` from D3 to illustrate library-based sorting, and relies on D3 version 7.3.0 for these utilities. The visualization itself is minimal—a single HTML page with a large styled message—while the core content lives in the script’s output.

How to use function "map"

This example demonstrates how to use the JavaScript `map` function on an array. It defines an array `[10, 20, 30]` and applies `map` to multiply each element by 2, logging the result to the console. The React application does not render any visible content; instead, the example focuses on the logic of transforming data with `map` within a React component structure. It uses React and ReactDOM from the UMD builds, with all logic contained in the `index.js` file.

test1

This example demonstrates basic JavaScript array manipulation and object reduction, with output visible only in the browser console. The code uses standard array methods including `sort`, `map`, and `reduce` to square numbers, create transformed objects, compute a cumulative division, and convert an array of key-value pairs into a single object. No D3-specific APIs are called; the page merely includes D3 v7 via CDN and renders an empty body with large text styling. The visualization is limited to a blank screen, with all behavior occurring through console logging.
