What is the purpose of the WhatIf option in destructive commands?

Explanation:
WhatIf is a dry-run safety feature for destructive commands. It runs the command in a simulation mode and reports exactly what would change if the command were executed, without actually making any modifications. This lets you verify targets and scope before committing to the action, helping prevent accidental data loss or system changes. In many modern CLIs, this is invoked with a long-form flag like --whatif, which clearly signals the preview behavior. Other forms like -DryRun or -Preview aim for the same idea, but the double-dash version is the one shown here as the WhatIf option. The key is that the flag prompts the tool to describe the impending changes rather than perform them, giving you a safe checkpoint before execution.
