throw is an atomic PowerShell topic inside Errors & Diagnostics. The example below uses the actual construct named by the lesson rather than a generic placeholder.
Focus on what throw changes: the input, binding, control path, object state, collection, runtime effect, or language contract. Then alter one value and verify that the behavior changes for a reason specific to this feature.
Topic-specific example

powershell
Try It Live
throw [System.ArgumentException]::new("quantity must be positive")
Edge case / engineering note
Exercise both the success path and the failure path; verify what is caught, propagated, or cleaned up rather than only checking printed output.
