<p>I have a one-dimensional array of strings in JavaScript that I'd like to turn into a comma-separated list. Is there a simple way in garden-variety JavaScript (or jQuery) to turn that into a comma-separated list? (I know how to iterate through the array and build the string myself by concatenation if that's the only way.)</p>

The
Array.prototype.join()
method:
```
```
var arr = ["Zero", "One", "Two"];

document.write(arr.join(", "));
```
```
