For most of the examples given in this tutorial, you will find Try itoption, so just make use of it and enjoy your learning.

Local Environment Setup

If you are still willing to set up your environment for Node.js, you need the following two softwares available on your computer, (a) Text Editor and (b) The Node.js binary installables.

Text Editor

This will be used to type your program. Examples of few editors include windows Notepad, OS Edit command, brief, Epsilon, EMACS, and vim or vi.

Name and version of text editor can vary on different operating systems. for example, Notepad will be used on windows, and vim or vi can be used on windows as well as Linux or UNIX.

The files you create with your editor are called source files and contain program source code. The source files for Node.js programs are typically named with the extension ".js".

Before starting your programming, make sure you have one text editor in place and you have enough experience to write a computer program, save it in a file, and finally execute it.

The Node.js Runtime

The source code written in source file is simply javascript. The Node.js interpreter will be used to interpret and execute your javascript code.
Node.js distribution comes as a binary installable for SunOS , Linux, Mac OS X, and Windows operating systems with the 32-bit (386) and 64-bit (amd64) x86 processor architectures.

Following section guides you on how to install Node.js binary distribution on various OS.

Download Node.js archive

Download latest version of Node.js installable archive file from Node.js Downloads. At the time of writing this tutorial, following are the versions available on different OS.

OS

Windows

node-v6.3.1-x64.msi

Linux

node-v6.3.1-linux-x86.tar.gz

Mac

node-v6.3.1-darwin-x86.tar.gz

SunOS

node-v6.3.1-sunos-x86.tar.gz

Installation on UNIX/Linux/Mac OS X, and SunOS

Based on your OS architecture, download and extract the archive node-v6.3.1-osname.tar.gz into /tmp, and then finally move extracted files into /usr/local/nodejs directory. For example:

Add /usr/local/nodejs/bin to the PATH environment variable.

OS

Output

Linux

export PATH=$PATH:/usr/local/nodejs/bin

Mac

export PATH=$PATH:/usr/local/nodejs/bin

FreeBSD

export PATH=$PATH:/usr/local/nodejs/bin

Installation on Windows

Use the MSI file and follow the prompts to install the Node.js. By default, the installer uses the Node.js distribution in C:\Program Files\nodejs. The installer should set the C:\Program Files\nodejs\bin directory in window's PATH environment variable. Restart any open command prompts for the change to take effect.

Verify installation: Executing a File

Create a js file named main.js on your machine (Windows or Linux) having the following code.

Now execute main.js file using Node.js interpreter to see the result:

If everything is fine with your installation, this should produce the following result:
