You must prefix your execution of the *.Js file with the node executable to add context, as if to say, "open this file with the node scripting engine, rather than the default Microsoft scripting engine, which does not recognize the 'console' object."

Therefore, instead of simply providing the name of the .Js file, like so:

<pre><code>myFirst.js
</code></pre>

Change it to:

<pre><code>node myFirst.js
</code></pre>

The name of the *.js file acts as a parameter to the node executable, which is then executed, providing you with your "Sweet.. Welcome to Node.js" statement.

To answer this, first we need to understand that the error is caused because it is being executed by Windows Script Host.

Now, run the code from your cmd promt with the following syntax:

<pre><code>&gt;node myFirst.js
</code></pre>

or

<pre><code>&gt;node &lt;application_name&gt;.js
</code></pre>

this will allow the Node.js application to open through V8 JavaScript engine(Google's).

P.S: Please reply back if this has helped in resolving your issue else post the problem you are facing after trying this.

I have the same problem in windows 8 with my example <code>hello_word.js</code>:

<ol>
<li>So I install the node js <code>7.7.2 vesion</code> in disk <code>D</code>, because there is question of rights and System sécurity when you install in disk <code>c</code>, so it is more difficult to work in disk <code>c</code></li>
<li>when I finished the install wizard, I lunch "cmd" and then I change my position to the <code>d:/ nodejs</code> by using <code>cd d:/nodejs</code></li>
<li>then there is two issues: 

<ol>
<li>execute the <code>node hello_word.js</code></li>
<li>or at first execute <code>node</code>, so now you are in the node session, then execute <code>requiere('./hello_word.js')</code></li>

<a href="https://stackoverflow.com/a/35834995/4537">HALAR's helpful answer</a>:

<ul>
<li>explains that <code>*.js</code> file are by default executed by Microsoft's obsolescent WSH (<a href="https://en.wikipedia.org/wiki/Windows_Script_Host" rel="noreferrer">Windows Script Host</a>) JavaScript engine (JScript) rather than Node.js,</li>
<li>and that passing a Node.js <code>*.js</code> script directly to the <code>node.exe</code> executable ensures its proper execution.</li>
</ul>

Alternatively, you can reconfigure file-extension associations so as to make <code>*.js</code> files execute with the Node.js engine by default:

<ul>
<li>Open a PowerShell console window.</li>
<li>Execute the following, which changes the association of the <code>.js</code> extension in the Windows registry (which takes effect for the current user account only, but, conversely, doesn't require elevation):</li>
</ul>

<pre class="lang-powershell prettyprint-override"><code>New-Item -Force HKCU:\SOFTWARE\Classes\NodeJSFile\shell\Open\Command -Value "`"$((Get-Command node.exe).Source)`" `"%1`" %*"
New-Item -Force HKCU:\SOFTWARE\Classes\.js -Value 'NodeJSFile'
</code></pre>

From that point on, invoking <code>*.js</code> files directly will execute them with Node.js (<code>node.exe</code>).

Note, however, that you'll have to do this on every machine that you want to behave this way.
