import { Worker, isMainThread, setEnvironmentData, getEnvironmentData, } from 'node:worker_threads'; if (isMainThread) { setEnvironmentData('Hello', 'World!'); const worker = new Worker(__filename); } else { console.log(getEnvironmentData('Hello')); // Prints 'World!'. } @param keyAny arbitrary, cloneable JavaScript value that can be used as a {Map} key.
