/**
 * @description
 * Use this helper return the index of the first element in the array where predicate is true, and -1 otherwise.
 *
 * This function behaves similarly to `Array.prototype.findIndex`, but with added error handling:
 * - If the predicate throws an error for any element, the error is handled via the onError callback.
 * - Allows for custom error handling through the onError option.
 *
 * @param {Array<TInput>} collection The array of items to test.
 * @param {Predicate<TInput>} predicate A function that tests each element of the array. Called once for each item in the array.
 * @param {{ onError?: OnError<TInput> }} options An optional object for error handling.
 *
 * @returns {number} The index of the first element that satisfies the test. Returns -1 if no element matches.
