Answer 1

Pretty simple using Array.prototype.join()

  var data = ['a','b','c','d']; console.log(data.join('|')); 

Answer 2

You can use array.join ,

var pipe_delimited_= string_array.join("|");

DEMO

 var string_array = ['a','b','c','d']; var pipe_delimited = string_array.join("|"); console.log(pipe_delimited); 

Answer 3

Try using array's join() method.The join() method joins array elements into a string.

  var arr = ['a','b','c','d'];//your aray var string =arr.join("|"); console.log(string);
