Examples

Example 1

import * as A from "./array.ts";
import { pipe } from "./fn.ts";

const update = A.update(100); // Update the value 100
const arr = [1, 2, 3];

const result1 = pipe(arr, update(0)); // [100, 2, 3]
const result2 = pipe(arr, update(1)); // [1, 100, 3]
const result3 = pipe(arr, update(4)); // [1, 2, 3]
