js - convert a whole array of strings into a string in which strings are separated by |

Question

I have an array full of strings like [a,b,c,d]. I want to know the efficient way of converting this into 'a|b|c|d' using Javascript.

Thanks.

Use the .join() method... ['a','b','c','d'].join('|') -> "a|b|c|d" — Josh Crozier

I'm really curious why you posted a question about doing the opposite in Ruby just one minute before posting this one. — Jordan Running

haha @Jordan quite good question. I'm learning both ruby and Javascript and as a part of that, I'm learning strings in both. — Ninja Boy

@NinjaBoy quite honestly you should have been able to research both easily. Research prior to asking questions here is expected — charlietfl

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

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);

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);
