pipe（）將如何在節點js中執行讀取和寫入操作？

Question

var fs = require("fs"); 

var readStream= fs.createReadStream('input.txt'); 

var writeStream=fs.createWriteStream('output.txt'); 

readStream.pipe(writeStream); 

console.log("hello...world"); 

在上述程序中，readStream和writeStream操作由管function..what做的是內部碼和內部處理中pipe()發生？
