The process.chdir() method changes the current working directory of the Node.js process or throws an exception if doing so fails (for instance, if the specified directory does not exist).

import { chdir, cwd } from 'node:process';

console.log(`Starting directory: ${cwd()}`);
try {
  chdir('/tmp');
  console.log(`New directory: ${cwd()}`);
} catch (err) {
  console.error(`chdir: ${err}`);
}

This feature is not available in Worker threads.
