Julia error VS Code and Juno / Error Julia VS Code and Juno

Question

When I try to make a basic program like this in VS Code:

n = 0
while n < 10
    n+=1
    println(n)
end

i get this mistake:

    ERROR: syntax: unexpected end

I tried to do the same program on Juno (the Juliapro version) and I get this other error, which also doesn’t make sense to me:

    LoadError: UndefVarError: n not defined

what mistake I’m making?

According to the documentation of Julia, you must do so:

julia> i = 1;

julia> while i <= 5
           println(i)
           global i += 1
       end

The error that appeared is due to variable n be declared out of scope as is described here, example:

julia> a
ERROR: UndefVarError: a not defined

julia> a = 1;

julia> a
1

About the scope of variables you can also find in documentation
