   * 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('node: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('node:util');
   * const assert = require('node:assert');
   *
   * const o1 = {
   *   b: [2, 3, 1],
   *   a: '`a` comes before `b`',
   *   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`',
   *   b: [2, 3, 1],
   * };
   * assert.strict.equal(
   *   inspect(o1, { sorted: true }),
   *   inspect(o2, { sorted: true }),
   * );
   * ```
   *
   * The `numericSeparator` option adds an underscore every three digits to all
   * numbers.
   *
   * ```js
   * const { inspect } = require('node:util');
   *
   * const thousand = 1_000;
   * const million = 1_000_000;
   * const bigNumber = 123_456_789n;
