javascript - What is byte fixed size length? -


i have connect , send message server. needs message length , manual states:

message length: fixed size (4 bytes)

how fixed length size in javascript/node.js? suppose message is: "hello, hand shake."

use buffer:

var buffer = new buffer(4, 'hex'); buffer.write('aabbaaaa'); // 10101010 10111011 10101010 10101010

docs:
http://nodejs.org/api/buffer.html#buffer_buffer

useful nodejitsu article:
