How do I check if an array is empty in Julia?

Question

I am trying to see if there's a handy way to check if an array in Julia is empty or not.

Answer 1

In Julia you can use the isempty() function documented here.

julia> a = []
0-element Array{Any,1}

julia> isempty(a)
true

julia> length(a)
0

julia> b = [1]
1-element Array{Int64,1}:
 1

julia> isempty(b)
false

Note that I included the length check as well in case that will help your use case.
