Introduction

mayfail makes risky operations explicit without changing their shape more than necessary.

Every call returns a Result<T> tuple:

type Result<T> = [T, null] | [null, Error];

The success value and error always occupy the same position. There is no wrapper object and no hidden control flow.

const [payload, error] = mayfail(() => JSON.parse(input));

Use it where throwing is more noise than signal, while keeping synchronous code synchronous and awaiting asynchronous code normally.
