True Myth is a TypeScript library providing type-safe Maybe, Result, and Task types for handling null values, errors, and async operations in a functional style. It offers well-tested wrappers and helper functions inspired by Rust's Option and Result types.

Use cases

• avoid null and undefined errors in TypeScript
• handle errors with type safety instead of exceptions
• make async error handling explicit with a safer Promise
• adopt functional programming patterns like Maybe and Result in JavaScript
• model optional values explicitly in an API
• pipe data through composable transformations

When to choose

• you want Rust-like Option and Result ergonomics in TypeScript
• your team struggles with null pointer errors and unhandled promise rejections
• you want a small, well-tested, zero-dependency functional core
• you prefer explicit error handling over try/catch exceptions

When to avoid

• you prefer exception-based error handling idioms
• your project cannot use strict TypeScript with ES modules
• you need a full functional programming toolkit like fp-ts with advanced type-level features
