collapse a vector as comma separated string in julia

I have 1-d vector of values. I want to convert them into a string with values separated by comma. Is there an easy way in Julia to do this? Something like collapse in r

{julia}
julia> x = [24,122,63,24,83,56,54,175,11,11,24,51,85,92,74,500,80,127,126,59,111,155,132,202,64,164,1301]

#I want output like this as a string
#24,122,63,24,83,56,54,175,11,11,24,51,85,92,74,500,80,127,126,59,111,155,132,202,64,164,1301,27

#I have tried something like this
[julia> [print(i,",") for i in x]
24,122,63,24,83,56,54,175,11,11,24,51,85,92,74,500,80,127,126,59,111,155,132,202,64,164,1301,27-element Array{Void,1}:
 nothing
 nothing
 nothing
 nothing
 nothing
 nothing
 nothing
 nothing
 nothing
 nothing
 nothing
 nothing
 nothing
 nothing
 nothing
 nothing
 nothing
 nothing
 nothing
 nothing

Print most of the values with an ordinary loop, then print the last item (to eliminate the trailing comma):

julia> for i in @view x[1:end-1]
           print(i, ',')
       end; print(x[end])
24,122,63,24,83,56,54,175,11,11,24,51,85,92,74,500,80,127,126,59,111,155,132,202,64,164,1301

You can also join each item in the iterable with a comma:

julia> print(join(x, ','))
24,122,63,24,83,56,54,175,11,11,24,51,85,92,74,500,80,127,126,59,111,155,132,202,64,164,1301

Also this, which is simpler: print(string(x)[2:(end - 1)]).
