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