How do I set variable scope in PowerShell?

In PowerShell, you can set variable scope using the -Scope parameter. The common scopes are Global, Local, and Script.

Can you give me an example of using a global variable?

Sure! You can declare a global variable like this: $Global:myVar = 'Hello World'. This variable can be accessed from any scope.

What about script scope? How is it different?

Script scope means the variable is accessible only within the script where it's defined. Use $Script:myVar = 'Hello' for that.

Are there any best practices for using variable scopes?

Yes, it's best to limit the use of global variables to avoid conflicts and maintain clean code. Use local and script scopes when possible.
