The best option is to use the .join() method:

arrray.join(","");

In JavaScript, you can transform an array of integers into a comma-separated string using the .join() method. Here's how:

const numbers = [1, 2, 3, 4, 5];
const commaSeparated = numbers.join(",");
console.log(commaSeparated); // Output: "1,2,3,4,5"

Explanation:

  • .join(",") joins all elements in the array with a comma , as the separator.

You can use any separator you like by changing the string inside join().
