/**
 * `findLastIndexOr(target, predicate, or)`
 *
 * Returns the index of the last element in `target` that satisfies the provided `predicate` function. If no element satisfies the predicate, returns `or`.
 *
 * ```ts
 * findLastIndexOr([1, 3, 2, 4], (x) => x > 2, -1); // 3
 * findLastIndexOr([1, 2, 3, 4], (x) => x > 5, -1); // -1
 * ```
 *
 * ```ts
 * pipe(
 *     [1, 3, 2, 4],
 *     findLastIndexOr((x) => x > 2, -1),
 * ); // 3
 * pipe(
 *     [1, 2, 3, 4],
 *     findLastIndexOr((x) => x > 5, -1),
 * ); // -1
 * ```
