## WebWorker.evaluateHandle() method
|
|
|
|
The only difference between `worker.evaluate` and `worker.evaluateHandle` is that `worker.evaluateHandle` returns in-page object (JSHandle). 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 \[(await worker.executionContext()).evaluateHandle(pageFunction, ...args)\](\#executioncontextevaluatehandlepagefunction-args).
