worker.stdout
这是一个可读流,它包含在工作线程中写入到 process.stdout 的数据。如果在 Worker 构造函数中没有传入 stdout: true,那么数据将被传输到父线程的 process.stdout 流中。
【This is a readable stream which contains data written to process.stdout
inside the worker thread. If stdout: true was not passed to the
Worker constructor, then data is piped to the parent thread's
process.stdout stream.】
