Examples

Example 1

import * as O from "./option.ts";
import * as N from "./number.ts";

const Eq = O.getEq(N.EqNumber);

const result1 = Eq.equals(O.some(1))(O.some(2)); // false
const result2 = Eq.equals(O.some(1))(O.some(1)); // true
const result3 = Eq.equals(O.none)(O.none); // true
const result4 = Eq.equals(O.some(1))(O.none); // false
