Neotype Extensions

Default implementations for Neotype equivalence relations, total orders, and semigroups for built-in JavaScript objects

Features

Neotype Extensions provides default implementations for the Neotype Eq, Ord, and Semigroup interfaces for built-in JavaScript objects and their corresponding TypeScript definitions, including:

• Primitives: boolean, number, bigint, string, and symbol
• Generic containers:
  • Array and ReadonlyArray
  • Tuple literals and readonly tuple literals
  • Set and ReadonlySet
  • Map and ReadonlyMap
• Dates, Promises, and Functions
• Typed arrays

The specific implementations are as follows:

Install

Neotype Extensions is available on NPM.

npm install @neotype/extensions

Working with modules

This library provides a suite of ES6 modules. A .js suffix is required in all import statements. There are no exports. When imported, each module will augment a global object.

import "@neotype/extensions/number.js";
import "@neotype/extensions/string.js";
import "@neotype/extensions/boolean.js";
import "@neotype/extensions/promise.js";
// etc.

See each module's documentation for recommended import practices.
