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)<!-- -->.

| [evaluate(pageFunction, args)](./puppeteer.jshandle.evaluate.md) | | This method passes this handle as the first argument to <code>pageFunction</code>. If <code>pageFunction</code> returns a Promise, then <code>handle.evaluate</code> would wait for the promise to resolve and return its value. |
