findIndexOrElse

Array.findIndexOrElse(target, predicate, orElse)

Returns the index of the first element in target that satisfies the provided predicate function. If no element satisfies the predicate, calls orElse with the original array.

Example

ts
import { Array } from "@monstermann/array";

Array.findIndexOrElse(
    [1, 2, 3, 4],
    (x) => x > 2,
    () => -1,
); // 2

Array.findIndexOrElse(
    [1, 2, 3, 4],
    (x) => x > 5,
    (arr) => arr.length,
); // 4
ts
import { Array } from "@monstermann/array";

pipe(
    [1, 2, 3, 4],
    Array.findIndexOrElse(
        (x) => x > 2,
        () => -1,
    ),
); // 2

pipe(
    [1, 2, 3, 4],
    Array.findIndexOrElse(
        (x) => x > 5,
        (arr) => arr.length,
    ),
); // 4
