JSHandles can be created with the [page.evaluateHandle](./puppeteer.page.evaluatehandle.md) method. Signature: ```typescript export declare class JSHandle ``` ## Remarks The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `JSHandle` class. ## Example ```js const windowHandle = await page.evaluateHandle(() => window); ``` JSHandle prevents the referenced JavaScript object from being garbage-collected unless the handle is [disposed](./puppeteer.jshandle.dispose.md). JSHandles are auto- disposed when their origin frame gets navigated or the parent context gets destroyed. JSHandle instances can be used as arguments for [Page.$eval()](./puppeteer.page._eval.md), [Page.evaluate()](./puppeteer.page.evaluate.md), and [Page.evaluateHandle()](./puppeteer.page.evaluatehandle.md). ## Methods | Method | Modifiers | Description | | --- | --- | --- | | [asElement()](./puppeteer.jshandle.aselement.md) | | | | [dispose()](./puppeteer.jshandle.dispose.md) | | Stops referencing the element handle, and resolves when the object handle is successfully disposed of. | | [evaluate(pageFunction, args)](./puppeteer.jshandle.evaluate.md) | | This method passes this handle as the first argument to pageFunction. If pageFunction returns a Promise, then handle.evaluate would wait for the promise to resolve and return its value. | | [evaluateHandle(pageFunction, args)](./puppeteer.jshandle.evaluatehandle.md) | | This method passes this handle as the first argument to pageFunction. | | [executionContext()](./puppeteer.jshandle.executioncontext.md) | | Returns the execution context the handle belongs to. | | [getProperties()](./puppeteer.jshandle.getproperties.md) | | The method returns a map with property names as keys and JSHandle instances for the property values. | | [getProperty(propertyName)](./puppeteer.jshandle.getproperty.md) | | Fetches a single property from the referenced object. | | [jsonValue()](./puppeteer.jshandle.jsonvalue.md) | | | | [toString()](./puppeteer.jshandle.tostring.md) | | Returns a string representation of the JSHandle. |
