Selects objects from indexed collections, such as arrays and hash tables. Array indexes are zero-based, so the first object is indexed as[0]. You can also use negative indexes to get the last values. Hash tables are indexed by key value. ...
Unless the array is explicitly typed by casting, you can append any type of value to the array, as follows: PowerShell Afrita $a = 1,2,3 $a += 2 $a Output Afrita 1 2 3 2 and PowerShell Afrita $a += "String" $a Output Afrita 1 2 3 2 String When the value o...
