Go 1.20 introduced automatic seeding of the
[`math/rand`](/pkg/math/rand) global random number generator,
controlled by the [`randautoseed` setting](/pkg/math/rand/#Seed).

Go 1.20 introduced the concept of fallback roots for use during certificate verification,
controlled by the [`x509usefallbackroots` setting](/pkg/crypto/x509/#SetFallbackRoots).

Go 1.20 removed the preinstalled `.a` files for the standard library

Что касается JavaScript (в браузере и NodeJS), раньше там использовали для этой цели
<abbr title="callback">"обратные вызовы"</abbr>. Что выливалось в
<a href="http://callbackhell.ru/" class="external-link" target="_blank">ад обратных вызовов</a>.

In früheren Versionen von NodeJS / Browser JavaScript hätten Sie „Callbacks“ verwendet. Was zur <a href="http://callbackhell.com/" class="external-link" target="_blank">Callback-Hölle</a> führt.
