method WebWorker.prototype.evaluate
import { WebWorker } from "https://dotland.deno.dev/x/puppeteer@16.2.0/vendor/puppeteer-core/puppeteer/types.d.ts";

If the function passed to the worker.evaluate returns a Promise, then worker.evaluate would wait for the promise to resolve and return its value. If the function passed to the worker.evaluate returns a non-serializable value, then worker.evaluate resolves to undefined. DevTools Protocol also supports transferring some additional values that are not serializable by JSON: -0, NaN, Infinity, -Infinity, and bigint literals. Shortcut for await worker.executionContext()).evaluate(pageFunction, ...args).
