<p>ElementHandle prevents the DOM element from being garbage-collected unless the handle is <a href="/next/api/puppeteer.jshandle.dispose">disposed</a>. ElementHandles are auto-disposed when their origin frame gets navigated.</p>
<p>ElementHandle instances can be used as arguments in <a href="/next/api/puppeteer.page._eval">Page.$eval()</a> and <a href="/next/api/puppeteer.page.evaluate">Page.evaluate()</a> methods.</p>
<p>If you&#x27;re using TypeScript, ElementHandle takes a generic argument that denotes the type of element the handle is holding within. For example, if you have a handle to a <code>&lt;select&gt;</code> element, you can type it as <code>ElementHandle&lt;HTMLSelectElement&gt;</code> and you get some nicer type checks.</p>
<p>The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the <code>ElementHandle</code> class.</p>
