function markAsUncloneable
#markAsUncloneable(object: object): voidMark an object as not cloneable. If object is used as message in
a port.postMessage() call, an error is thrown. This is a no-op if object is a
primitive value.
This has no effect on ArrayBuffer, or any Buffer like objects.
This operation cannot be undone.
const { markAsUncloneable } = require('node:worker_threads');
const anyObject = { foo: 'bar' };
markAsUncloneable(anyObject);
const { port1 } = new MessageChannel();
try {
// This will throw an error, because anyObject is not cloneable.
port1.postMessage(anyObject)
} catch (error) {
// error.name === 'DataCloneError'
}
