Basic Usage

mayfail returns [value, null] on success and [null, error] on failure.

import { mayfail } from "mayfail";

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

if (error) {
  console.error(error.message);
} else {
  console.log(payload);
}

Thrown values that are not Error instances are normalized to an Error, so the error branch remains consistent.

For operations that return a promise, see Async.
