Don’t do that #15: Use Add method when creating an array with multiple elements

Don’t do that: An empty array is created and then the elements are added.

$array = @()

$array += 'User1'
$array += 'User2'
$array += 'User3'
$array += 'User4'
$array += 'User5'

$array = @()

$array += 'User1'

$array += 'User2'

$array += 'User3'

$array += 'User4'

$array += 'User5'

Do that: There are several ways to do that with one-liners:

$array = @('User1', 'User2', 'User3', 'User4', 'User5')
$array = 'User1', 'User2', 'User3', 'User4', 'User5'
$array = 'User1,User2,User3,User4,User5'.Split(',')
$array = .{$args} User1 User2 User3 User4 User5
$array = echo User1 User2 User3 User4 User5 # echo is an alias

$array = @('User1', 'User2', 'User3', 'User4', 'User5')

$array = 'User1', 'User2', 'User3', 'User4', 'User5'

$array = 'User1,User2,User3,User4,User5'.Split(',')

$array = .{$args} User1 User2 User3 User4 User5

$array = echo User1 User2 User3 User4 User5 # echo is an alias
