What do you call these? [array][string][int]

What are these called? When scripting in powershell I can use them to set or convert the data type of my variable, but what is the term for this? Is there an official doc for these?

Example:

$var = @("hello","world")  If ($var -is [array]) { write-host "$var is an array" }
