Examples

Example 1

import { or } from "./predicate.ts";
import { string, number } from "./refinement.ts";
import { pipe } from "./fn.ts";

// A Refinement is also a Predicate
const stringOrNumber = pipe(
  string,
  or(number),
);

const result1 = stringOrNumber("Hello"); // true
const result2 = stringOrNumber(1); // true
const result3 = stringOrNumber({}); // false
