How to split an array into single quotes and comma separated list in javascript

for instance if i have an array in javascript 

var productIds = ["abc", "xyz", "123"]; //having string elements

my desired output is not only to comma separate the array but surround each element with quotes.

'abc', 'xyz', '123'

I can do up to join, productIds.join(', ') but how to surround with quotes?

Add the quotes into the join and then wrap the resulting string in quotes as well. No need to add any extra overhead when it can be done more efficiently and be more readable.

"'" + myArray.join("', '") + "'";

The only case where this fails is with an empty array, so you can just test length in that case (the brackets aren't necessary, they're just for readability again):

myArray.length ? ( "'" + myArray.join("', '") + "'" ) : '';

You can use .map():

var quotedIds = productIds.map(function(id) { return "'" + id + "'"; }).join(", ");

The .map() function is available in newer browsers; if you need your code to work in an older browser, you can either include a shim or else simply implement that as a simple loop:

var quotedIds = [];
for (var i = 0; i < productIds.length; ++i)
  quotedIds.push("'" + productIds[i] + "'");
quotedIds = quotedIds.join(", ");
