Creating an object with multiple values for one key

Question

I have an array of string for example like this:

var names = ["sam", "john", "tom", "travis", "jack"]

And I need to create JavaScript object which will contain all these names separated by , by one key.

Look what I want:

var obj = {names : "sam, john, tom, travis, jack"}

I'm not familiar with JavaScript. I understand that I need to loop through my array of string and somehow append values to my object.

I am using jQuery if there's something in that which would help.

did you make any attempt so far? do you have some code to improve? — Paolo

why do you even want to do this? You have more control over an array than a comma separated list — charlietfl

Note that that isn't multiple values for one key. It's a single value: A string. — T.J. Crowder

Why not use use var obj = {names : ["sam", "john", "tom", "travis", "jack"]}? — Makaze

Frankly, that's a single line of simple JavaScript, but you do not give the impression you've actually tried. Check out "join" on mdn. — ddaa

Well, sure you could use Array.join

var obj = { names: names.join(", ") };

MDN

Summary

The join() method joins all elements of an array into a string.

Syntax

str = arr.join([separator = ','])

separator Optional. Specifies a string to separate each element of the array. The separator is converted to a string if necessary. If omitted, the array elements are separated with a comma.

Use .toString() in javascript.The toString() method converts an array into a String and returns the result.The returned string will separate the elements in the array with commas.

var obj = { names : names.toString() };

FIDDLE
