**On VS Code** :

I am trying to create a named array, but it throws this error:  
ERROR: MethodError: reducing over an empty collection is not allowed; consider supplying `init` to the reducer

My code is:

```julia
using NamedArrays
NamedArray([1,2,3], ["A", "B", "C"])

```

I am getting this error on VS Code only, which is strange. Maybe something is wrong with VS Code Julia extension.

Works just fine for me, both evaluating inline in the editor and in the built in REPL

Thank you for the answer. I marked as resolved - looks like it is a user specific issue. The strange thing is I am having an error but code is being executed correctly, outputting the same array as yours.
