What is the difference between local and global scope in PowerShell scripts?

What is the difference between local and global scope in PowerShell scripts?

In PowerShell, local scope refers to variables that are accessible only within the current function or script, while global scope allows variables to be accessed from anywhere in the session.

Can you give me an example of a local variable?

Sure! In a function, if you declare a variable like $localVar = 'Hello', it can only be used within that function.

And how do I create a global variable?

You can create a global variable by using the global: prefix, like this: $global:globalVar = 'World'. This variable can be accessed from any function or script.

What happens if I have a local and a global variable with the same name?

If you have a local and a global variable with the same name, the local variable will take precedence within its scope.
