In a script, when a command-let or other executable statement errors out, is there a try/catch type of mechanism to recover from these errors? I haven't run across one in the documentation.

If a terminating error occurs in the try block, PowerShell searches for an appropriate catch block. If one is found, the statements in the catch block are executed. The catch block can specify one or more error types.
What is PowerShell Error Handling? Quick Definition: Error handling in PowerShell is a process of analyzing your code for where exceptions could occur, for what exceptions could happen, and then writing code that anticipates and handles those exceptions.
Use the try block to define a section of a script in which you want PowerShell to monitor for errors. When an error occurs within the try block, the error is first saved to the $Error automatic variable. PowerShell then searches for a catch block to handle the error.
GetType(). FullName to view the exception message for the last error that occurred. Going back to the PowerShell console, rerun the New-Item command with a non-existent path, then run the $Error command to find the exception message.
You use a Trap [exception-type] {} block before the code you want to handle exceptions for.
