Last iteration of a loop in JavaScript

Question

I want to do something like this:

for (var i=1; i<=10; i++) {
   document.write(i + ",");
}

It shows a result like:

1,2,3,4,5,6,7,8,9,10,

But I want to remove the last ",", and the result should be like this:

1,2,3,4,5,6,7,8,9,10

You should use .join instead:

var txt = [];                          //create an empty array
for (var i = 1; i <= 10; i++) {
    txt.push(i);                       //push values into array
}

console.log(txt.join(","));            //join all the value with ","
