Node.js v6.2.2 發布

看到Node.js這個名字，初學者可能會誤以為這是一個Javascript應用，事實上，Node.js采用C++語言編寫而成，是一個Javascript的運行環境。為什么采用C++語言呢？據Node.js創始人Ryan Dahl回憶，他最初希望采用Ruby來寫Node.js，但是后來發現Ruby虛擬機的性能不能滿足他的要求，后來他嘗試采用V8引擎，所以選擇了C++語言。既然不是Javascript應用，為何叫.js呢？因為Node.js是一個Javascript的運行環境。Node.js是一個后端的Javascript運行環境（支持的系統包括Linux、Windows和Mac等），這意味著你可以編寫系統級或者服務器端的Javascript代碼，交給Node.js來解釋執行，Node.js采用了Google Chrome瀏覽器的V8引擎，性能很好，同時還提供了很多系統級的API，如文件操作、網絡編程等。瀏覽器端的Javascript代碼在運行時會受到各種安全性的限制，對客戶系統的操作有限。相比之下，Node.js則是一個全面的后臺運行時，為Javascript提供了其他語言能夠實現的許多功能。
