What are some common errors with variables in PowerShell?

What are some common errors I might encounter with variables in PowerShell?

Common errors include uninitialized variables, scope issues, and type mismatches. Would you like examples?

Yes, please provide examples of uninitialized variables.

An uninitialized variable in PowerShell can lead to unexpected results. For instance, using $myVar without assigning it a value will return nothing.

What about scope issues? How do they affect variable usage?

Scope issues occur when a variable is defined in a different scope than where it's accessed. For example, a variable defined inside a function won't be available outside of it.

How can I avoid these errors in my scripts?

To avoid these errors, always initialize your variables, be mindful of scope, and use type constraints when necessary.
