# the specified iterable collection
# or 1D array
println(last(1:2:3))
println(last(5:10))
println(last([3, 5, 7, 9]))

3
10
9

Example 2:

# Julia program to illustrate
# the use of last() method

# Getting the last element of
# the specified 2D and 3D array
println(last([3 5; 7 9]))
println(last(["a" "b"; "c" "d"]))
println(last(cat([1 2; 3 4], [5 6; 7 8],
                 [2 2; 3 4], dims = 3)))
println(last(cat(["a" "b"; "c" "d"],
                 ["e" "f"; "g" "h"],
                 ["i" "j"; "k" "l"], dims = 3)))
