# Type integer
$myArrayOfIntegers = 1, 2, 3, 4

# Type Strings
$myArrayOfStrings = "1", "2", "3", "4"

Adding to an array

$myArrayOfIntegers = $myArrayOfIntegers + 5

Combining arrays together

$ArrOne = 1, 2, 3
$ArrTwo = 4, 5, 6

$ArrAll = $ArrOne + $ArrTwo

Multiple Variables

$String = "abc.def.gij"

$parts = $String.Split(".")

# output: abc
$parts[0]

#output: def
$parts[1]

#output: gij
$parts[2]
