Javascript console lesson 4 dynamic typing

I have been following everything so far with no issues, but when Mosh types in the console
typeof name, it come back with “string”

I just get an error message: the term typeof is not recognized as a name of a CMDlet, function, script file, or executable program.
check the spelling of the name, or if a path was included, verify that the path is correct then try again.

I cannot see what I am doing wrong.

The small white window on the right side is a browser console. You obviously used a windows console with PowerShell.
