Consider an array as the following:
[1,4,5,9]
The goal is to duplicate each value and append it next to it's copy in Julia, hence:
[1,1,4,4,5,5,9,9]
Is there a neat "julian" way of doing this avoiding a for- loop?

You can use the repeat function:
julia> v = [1, 4, 5, 9]
4-element Vector{Int64}:
1
4
5
9
julia> repeat(v; inner=2)
8-element Vector{Int64}:
1
1
4
4
5
5
9
9
