# Create an Array by separating the elements with commas:

# An array of several integer ([int]) values:
$array = 0, 1, 2, 3, 4, 5, 6, 7

# Using the range operator (..):
$array = 0..7

# Strongly typed:
[int[]] $stronglyTypedArray = 1, 2, 4, 8, 16, 32, 64, 128

# An empty array:
$array = @()

# An array with a single element:
