Daher kann es beim Ändern entweder des Quellobjekts oder der Kopie passieren, dass sich das andere Objekt ebenfalls ändert. Dieses Verhalten steht im Gegensatz zu dem einer <a href="/de/docs/Glossary/Deep_copy">Deep Copy</a>, bei der Quelle und Kopie vollständig unabhängig voneinander sind.</p> <p>Formeller ausgedrückt sind zwei Objekte <code>o1</code> und <code>o2</code> flache Kopien, wenn:</p> <ol> <li>Sie nicht dasselbe Objekt sind (<code>o1 !== o2</code>).</li> <li>Die Eigenschaften von <code>o1</code> und <code>o2</code> dieselben Namen in derselben Reihenfolge haben.</li> <li>Die Werte ihrer Eigenschaften gleich sind.</li> <li>Ihre Prototypketten gleich sind.</li> </ol> <p>Siehe auch die Definition von <em><a href="/de/docs/Glossary/Deep_copy">struktureller Äquivalenz</a></em>.</p> <p>Die Kopie eines Objekts, dessen Eigenschaften alle primitive Werte haben, passt sowohl zur Definition einer <a href="/de/docs/Glossary/Deep_copy">Deep Copy</a> als auch einer flachen Kopie. Es ist jedoch etwas sinnlos, über die Tiefe einer solchen Kopie zu sprechen, da keine verschachtelten Eigenschaften vorhanden sind und wir normalerweise im Kontext der Änderung verschachtelter Eigenschaften über Deep Copy sprechen.</p> <p>Bei flachen Kopien werden nur die Eigenschaften der obersten Ebene kopiert, nicht die Werte verschachtelter Objekte. Daher:</p> <ul> <li>Das Neuzuweisen von Eigenschaften der obersten Ebene der Kopie beeinflusst das Quellobjekt nicht.</li> <li>Das Neuzuweisen von verschachtelten Objekteigenschaften der Kopie beeinflusst jedoch das Quellobjekt.</li> </ul> <p>In JavaScript erzeugen alle standardmäßigen eingebauten Objektkopier-Operationen (<a href="/de/docs/Web/JavaScript/Reference/Operators/Spread_syntax">Spread-Syntax</a>, <a href="/de/docs/Web/JavaScript/Reference/Global_Objects/Array/concat"><code>Array.prototype.concat()</code></a>,

href="/de/docs/Web/JavaScript/Reference/Global_Objects/Array/from"><code>Array.from()</code></a> und <a href="/de/docs/Web/JavaScript/Reference/Global_Objects/Object/assign"><code>Object.assign()</code></a>) flache Kopien statt tiefer Kopien.</p> <p>Betrachten Sie das folgende Beispiel, in dem ein <code>ingredientsList</code>-Array-Objekt erstellt wird und dann ein <code>ingredientsListCopy</code>-Objekt durch das Kopieren dieses <code>ingredientsList</code>-Objekts erstellt wird.</p> <div class="code-example"><div class="example-header"><span class="language-name">js</span></div><pre class="brush: js notranslate"><code>const ingredientsList = ["noodles", { list: ["eggs", "flour", "water"] }]; const ingredientsListCopy = Array.from(ingredientsList); console.log(ingredientsListCopy); // ["noodles",{"list":["eggs","flour","water"]}] </code></pre></div> <p>Das Neuzuweisen des

Daher kann es beim Ändern entweder des Quellobjekts oder der Kopie passieren, dass sich das andere Objekt ebenfalls ändert. Dieses Verhalten steht im Gegensatz zu dem einer <a href=\"/de/docs/Glossary/Deep_copy\">Deep Copy</a>, bei der Quelle und Kopie vollständig unabhängig voneinander sind.</p>\n<p>Formeller ausgedrückt sind zwei Objekte <code>o1</code> und <code>o2</code> flache Kopien, wenn:</p>\n<ol>\n<li>Sie nicht dasselbe Objekt sind (<code>o1 !== o2</code>).</li>\n<li>Die Eigenschaften von <code>o1</code> und <code>o2</code> dieselben Namen in derselben Reihenfolge haben.</li>\n<li>Die Werte ihrer Eigenschaften gleich sind.</li>\n<li>Ihre Prototypketten gleich sind.</li>\n</ol>\n<p>Siehe auch die Definition von <em><a href=\"/de/docs/Glossary/Deep_copy\">struktureller Äquivalenz</a></em>.</p>\n<p>Die Kopie eines Objekts, dessen Eigenschaften alle primitive Werte haben, passt sowohl zur Definition einer <a href=\"/de/docs/Glossary/Deep_copy\">Deep Copy</a> als auch einer flachen Kopie. Es ist jedoch etwas sinnlos, über die Tiefe einer solchen Kopie zu sprechen, da keine verschachtelten Eigenschaften vorhanden sind und wir normalerweise im Kontext der Änderung verschachtelter Eigenschaften über Deep Copy sprechen.</p>\n<p>Bei flachen Kopien werden nur die Eigenschaften der obersten Ebene kopiert, nicht die Werte verschachtelter Objekte. Daher:</p>\n<ul>\n<li>Das Neuzuweisen von Eigenschaften der obersten Ebene der Kopie beeinflusst das Quellobjekt nicht.</li>\n<li>Das Neuzuweisen von verschachtelten Objekteigenschaften der Kopie beeinflusst jedoch das Quellobjekt.</li>\n</ul>\n<p>In JavaScript erzeugen alle standardmäßigen eingebauten Objektkopier-Operationen (<a

Daher kann es beim Ändern entweder des Quellobjekts oder der Kopie passieren, dass sich das andere Objekt ebenfalls ändert. Dieses Verhalten steht im Gegensatz zu dem einer Deep Copy, bei der Quelle und Kopie vollständig unabhängig voneinander sind.","title":"Shallow copy","toc":[{"text":"Siehe auch","id":"siehe_auch"}],"pageType":"glossary-definition"}}</script></body></html>
