You can use toString() method:

let arr = [12,12,43,53,56,7,854,3,64,35,24,67]; arr = arr.toString(); console.log(arr); console.log(typeof arr);

One solution is to use join method.

The join() method joins the elements of an array into a string, and returns the string.

let arr = [12,12,43,53,56,7,854,3,64,35,24,67] let strArr = arr.join(); console.log(strArr);

The join() method joins all elements of an array (or an array-like object) into a string.

var a = [12,12,43,53,56,7,854,3,64,35,24,67]; a.join(); // '12,12,43,53,56,7,854,3,64,35,24,67'

JS type coercion is sometimes useful.

var arr = [12,12,43,53,56,7,854,3,64,35,24,67], strArr = arr + ""; // <- "12,12,43,53,56,7,854,3,64,35,24,67"

Solution to this would be to use join()

let arr = [12,12,43,53,56,7,854,3,64,35,24,67] let strArr = arr.join();

Second you be to use toString()

 let arr = [12,12,43,53,56,7,854,3,64,35,24,67] let strArr = arr.toString();

Because you want to join by a comma, they are basically identical, but join allow you to chose a value separator.
