Combine and stack arrays in columns in julia

I am trying to combine two 1D arrays and stack them in columns,

a = [1 2 3]
b = [4 5 6]

# such that, they produce

     a b
c = [1 4
     2 5
     3 6]

# the python syntax for such operation is 
np.stack_column((a,b))

Please can someone suggest the julia syntax for this operation?

On of my friend suggested two ways of executing this,

1.   transpose(vcat(a,b))
     hcat(a', b')
  
2.   reshape(hcat(a,b), (3,2))

Both will create an output of

 Array{Int64,2}:
 1  4
 2  5
 3  6

3×2 Array{Int64,2}: 1 4 2 5 3 6
