Optionals   🦀

Rust-like error handling and options for TypeScript and Deno! This module allows you to remove null and undefined from your projects with the help of ES6 Symbols and helper functions. Inspired by Rust's Option and Result.

Why should you use Optionals?

The standard practice of returning null or undefined when no other value can be returned, leaves something to be desired as there is no way to tell where in the code said value came from. Rust's implementation of error handling (e.g. bubbling) also has many benefits that cannot be expressed in the normal try catch JS pattern.

This module provides a minimal, fast and simple way to create expressive functions and better pattern matching! 🚀

Type Systems

Optionals provides two type systems, Hard or Soft typing.

• Hard - Return types are actual values. Strict typing with rust-like exhaustive pattern matching!
• Soft - Return types are compiled away at runtime. A lightweight structure, ideal for small projects.
