# Using for construct

# [0, 0, 0]
for _x <- 0..2, do: 0

# [0, 2, 4, 6, 8]
for x <- 0..4, do: x * 2

# List of 5 random numbers
for _x <- 0..4, do: System.unique_integer([:positive])

# Using Enum.map

# [0, 0, 0]
Enum.map(0..2, fn _x -> 0 end)

# [0, 2, 4, 6, 8]
Enum.map(0..4, fn x -> x * 2 end)

# List of 5 random numbers
Enum.map(0..4, fn _x -> System.unique_integer([:positive]) end)
