Create comma-delimited string
提问by Urbycoz
I'm looking to find a neat way to create a comma-delimited string from an array. This is how I'm doing it now...
我正在寻找一种巧妙的方法来从数组创建逗号分隔的字符串。这就是我现在的做法...
for(i=0;i<10;i++)
{
str = str + ',' + arr[i];
}
str=str.substring(1)
return str;
... but it feels a bit untidy.
……不过感觉有点乱。

Array.prototype.join()is what you're looking for:
Array.prototype.join()是你要找的：
arr.join(',');

var arr = ['Hi', 'I', 'am', 'a', 'comma', 'separated', 'list'];
arr.join(','); // === "Hi,I,am,a,comma,separated,list"
