How do I initialize an empty array / vector of strings, and then push strings into it? When I do `t = Vector{String}` , I get this error when I then push into it:

```julia
push!(t, "a")
ERROR: MethodError: no method matching push!(::Type{Array{String,1}}, ::String)
Closest candidates are:
  push!(::Any, ::Any, ::Any) at abstractarray.jl:2252
  push!(::Any, ::Any, ::Any, ::Any...) at abstractarray.jl:2253
  push!(::Array{Any,1}, ::Any) at array.jl:940

```

and `t = Array{String}` results in the same error.

(I want to specify the type that the vector will be filled with in advance because the array will subsequently go into a namedtuple)

```julia
julia> t = String[]
String[]

julia> push!(t,"a string")
1-element Array{String,1}:
 "a string"

julia> t
1-element Array{String,1}:
 "a string"

```

Another way

```julia
julia> w = Vector{String}()
String[]

julia> push!(w,"another string")
1-element Array{String,1}:
 "another string"

julia> w
1-element Array{String,1}:
 "another string"

```
