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);You can read more about this here.

@Alexandru-IonutMihai, multumesc :). Same goes for your answer. :)
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.
arr + ""
