Absurdum is a Javascript utility library built with a focus on providing idempotent side-effect free functions and clear/readable modular source for tree shaking.

Features

• Explores the flexibility of Reduce
• Abstraction Free -> tree-shake friendly
• Functional -> all operators are side-effect free
• Polyfills -> includes operator polyfills for older browsers
• Isomorphic -> works consistently across all JS runtimes
• Typescript -> typings are provided for all operators
• Intellisense -> supports code completions + inline documentation
• Well Tested -> includes 600+ tests covering every aspect

Imports

This package works isomorphically in browsers and server-side JavaScript runtimes

Browsers

Import directly from the local path or a CDN

Top-level operator namespaces (ie [arrays, objects, strings]) can be imported from the index

<script type="module">
import { arrays, objects, strings } from 'path/to/absurdum/index.js'
</script>

The minified version can be imported from

<script type="module">
import { arrays, objects, strings } from 'path/to/absurdum/index.min.js'
</script>

Node

Install the package

npm install @vanillaes/absurdum

Top-level operator namespaces are provided

import { arrays, objects, strings } from '@vanillaes/absurdum';

Individual operators can also be imported from their parent namespaces

import { chunk, find } from '@vanillaes/absurdum/arrays';
import { assign, invert } from '@vanillaes/absurdum/objects';
import { camelCase, repeat } from '@vanillaes/absurdum/strings';

Note: Webpack's tree-shaking algorithm doesn't work with multi-layered exports. To optimize bundle size, prefer individual operator imports.

Usage

Import an operator and feed it some inputs

const input = ['a', 'b', 'c', 'd'];
const output = reverse(input);
console.log(output);
// > ['d', 'c', 'b', 'a']

Tip: For VSCode users. Input type-checking, intellisense, and inline documentation are all supported.
