): boolean

Sends data on the socket. The second parameter specifies the encoding in the case of a string. It defaults to UTF8 encoding. Returns `true` if the entire data was flushed successfully to the kernel buffer. Returns `false` if all or part of the data was queued in user memory.`'drain'` will be emitted when the buffer is again free. The optional `callback` parameter will be executed when the data is finally written out, which may not be immediately. See `Writable` stream `write()` method for more information.
