     *
     * The `showHidden` option allows [`WeakMap`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/WeakMap) and
     * [`WeakSet`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/WeakSet) entries to be
     * inspected. If there are more entries than `maxArrayLength`, there is no
     * guarantee which entries are displayed. That means retrieving the same [`WeakSet`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/WeakSet) entries twice may
     * result in different output. Furthermore, entries
     * with no remaining strong references may be garbage collected at any time.
     *
     * ```js
     * const { inspect } = require('util');
     *
     * const obj = { a: 1 };
     * const obj2 = { b: 2 };
     * const weakSet = new WeakSet([obj, obj2]);
     *
     * console.log(inspect(weakSet, { showHidden: true }));
     * // WeakSet { { a: 1 }, { b: 2 } }
     * ```
     *
     * The `sorted` option ensures that an object's property insertion order does not
     * impact the result of `util.inspect()`.
     *
     * ```js
     * const { inspect } = require('util');
     * const assert = require('assert');
     *
     * const o1 = {

     *   c: new Set([2, 3, 1])
     * };
     * console.log(inspect(o1, { sorted: true }));
     * // { a: '`a` comes before `b`', b: [ 2, 3, 1 ], c: Set(3) { 1, 2, 3 } }
     * console.log(inspect(o1, { sorted: (a, b) => b.localeCompare(a) }));
     * // { c: Set(3) { 3, 2, 1 }, b: [ 2, 3, 1 ], a: '`a` comes before `b`' }
     *
     * const o2 = {
     *   c: new Set([2, 1, 3]),
     *   a: '`a` comes before `b`',
