   * Tests if `value` is truthy.
   *
   * If `value` is not truthy, an `AssertionError` is thrown with a `message` property set equal to the value of the `message` parameter. If the `message` parameter is `undefined`, a default
   * error message is assigned. If the `message` parameter is an instance of an `Error` then it will be thrown instead of the `AssertionError`.
   * If no arguments are passed in at all `message` will be set to the string:`` 'No value argument passed to `assert.ok()`' ``.
   *
   * ```js
   * import * as assert from 'assert';
   *
   * assert.ok(true);
   * // OK
   * assert.ok(1);
   * // OK
   *
   * assert.ok();
