rl.close()

rl.close() 方法会关闭 readline.Interface 实例，并释放对 input 和 output 流的控制。当调用该方法时，将触发 'close' 事件。

🌐 The rl.close() method closes the readline.Interface instance and relinquishes control over the input and output streams. When called, the 'close' event will be emitted.

调用 rl.close() 并不会立即停止 readline.Interface 实例发出的其他事件（包括 'line'）。

🌐 Calling rl.close() does not immediately stop other events (including 'line') from being emitted by the readline.Interface instance.
