 * @private
 * @param {Array} array The array to query.
 * @param {Function} predicate The function invoked per iteration.
 * @param {boolean} [isDrop] Specify dropping elements instead of taking them.
 * @param {boolean} [fromRight] Specify iterating from right to left.
 * @returns {Array} Returns the slice of `array`.
