If the function passed to the `worker.evaluateHandle` returns a `Promise`, then `worker.evaluateHandle` would wait for the promise to resolve and return its value. Shortcut for `await worker.executionContext()).evaluateHandle(pageFunction, ...args)` <b>Signature:</b> ```typescript evaluateHandle<HandlerType extends JSHandle = JSHandle>(pageFunction: EvaluateHandleFn, ...args: SerializableOrJSHandle[]): Promise<JSHandle>; ``` ## Parameters | Parameter | Type | Description | | --- | --- | --- | | pageFunction | [EvaluateHandleFn](./puppeteer.evaluatehandlefn.md) | Function to be evaluated in the page context. | | args | [SerializableOrJSHandle](./puppeteer.serializableorjshandle.md)\[\] | Arguments to pass to <code>pageFunction</code>. | <b>Returns:</b> Promise<[JSHandle](./puppeteer.jshandle.md)> Promise which resolves to the return value of `pageFunction`.
