/**
 * This method is like `lastIndexOf` except that it performs a binary
 * search on a sorted `array`.
 *
 * @since 5.11.0
 * @category Array
 * @param array The array to inspect.
 * @param value The value to search for.
 * @returns Returns the index of the matched value, else `-1`.
 * @example
 *
 * ```js
 * sortedLastIndexOf([4, 5, 5, 5, 6], 5)
 * // => 3
 * ```
