 * @description
 * Finds the **index** of the first element in an array that satisfies a given predicate.

 *
 * @param {Array<T>} array The array to search
 * @param {ListIterateeCustom<T, unknown>} [predicate] The function invoked per iteration
 * @param {number} [fromIndex] The index to search from (default: `0`)
 * @returns {number} The index of the first element that satisfies the predicate, or `-1` if none found
