About Node.js
Developed originally in 2009 by Ryan Dahl, Node.js is an open-source, JavaScript run time environment. While the initial release only supported Linux, it has evolved as a truly cross-platform JavaScript run time environment for developing a wide variety of applications. The run time environment interprets JavaScript using Google's V8 JavaScript engine.
V8 is an open source execution engine built by Google in 2008. Written in C++, V8 compiles JavaScript source code to native machine code instead of interpreting it in real time.
The core functionality of Node.js is implemented in a JavaScript library. The Node.js bindings are written in C++. Node.js allows the creation of Web servers and networking tools using JavaScript and a collection of modules that handle various core functionality. Modules are provided for file system I/O, networking (such as HTTP, DNS, TCP, TLS/SSL, or UDP), binary data (buffers), cryptography functions, data streams and other core functions. Node.js' modules use an API designed to reduce the complexity of writing server applications
The Node.js distributed development project is governed by the Node.js Foundation and is facilitated by the Linux Foundation.
Where is Node.js primarily used?
Node.js is primarily used to build network applications using real time communication is required across end points. Node.js is good at I/O operation driven applications.
The biggest difference between Node.js and PHP is that while most functions in PHP block until completion (i.e. commands execute only after previous commands have completed), functions in Node.js are designed to be non-blocking (commands execute in parallel, and use call-backs to signal completion or failure of tasks)
Node.js brings event-driven programming to web servers, enabling development of fast web servers in JavaScript. Developers can create highly scalable servers without using threading, by using a simplified model of event-driven programming that uses call-backs to signal the completion of a task. Node.js was created because concurrency is difficult in many server-side programming languages, and often leads to poor performance. Node.js connects the ease of a scripting language with the power of network programming
Node.js is often used as part of the MEAN Stack which comprises of MongoDB, Express.js, Angular and Node.js, for building dynamic web sites and web applications.
