PowerShell Complete Course / Control Flow

trap

Learn trap in PowerShell with a construct-specific explanation, a unique example, a practical boundary, and a mastery check.

10 min read • Beginner

trap is an atomic PowerShell topic inside Control Flow. The example below uses the actual construct named by the lesson rather than a generic placeholder.

Focus on what trap 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-03-10-trap.ps1
powershell Try It Live 
trap { "caught: $($_.Exception.Message)"; continue }
1/0
"after"
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.
