prelude-js

A standard module for functional programming in JavaScript.

What

A minimalist collection of functions to support functional programming.

For example, it includes the following:

• Method of object as function.

  If you wanted to apply trim to all elements of a string[], you would do something like this:

  const runtime = [" deno ", " node.js"].map((v) => v.trim());

  Use string#trim.

  import { trim } from "https://deno.land/x/prelude_js@$VERSION/mod.ts";
  const runtime = [" deno ", " node.js"].map(trim);

Methods are provided as functions from any objects.

The independence of methods as functions is convenient for functional programming.
