Step by Step solution about How to resolve the algorithm Environment variables step by step in the JavaScript programming language

This code snippet uses the ActiveXObject to create a new ActiveX object, in this case, a WScript.Shell object. This object can be used to interact with the Windows operating system.

The code then uses the Environment method of the WScript.Shell object to get the environment variables for the current process. The item method of the Environment object is then used to get the value of the SYSTEMROOT environment variable.

Finally, the WScript.echo method is used to output the value of the SYSTEMROOT environment variable to the console.

Here is a breakdown of the code:

• var shell = new ActiveXObject("WScript.Shell"); creates a new WScript.Shell object.
• var env = shell.Environment("PROCESS"); gets the environment variables for the current process.
• WScript.echo('SYSTEMROOT=' + env.item('SYSTEMROOT')); outputs the value of the SYSTEMROOT environment variable to the console.

var shell = new ActiveXObject("WScript.Shell");
var env = shell.Environment("PROCESS");
WScript.echo('SYSTEMROOT=' + env.item('SYSTEMROOT'));
