Rendering comma separated list of links

Question

I\'m trying to output a list of comma separated links and this is my solution.

var Item = React.createComponent({
  render: function() {

    var tags = [],
         


        

Answer 1

Simply

{tags.map((tag, i) => 
    {i > 0 && ", "}
    
)}

In React 16 it can be done even more simpler:

{tags.map((tag, i) => [
    i > 0 && ", ",
    
])}
