how to separate a string by comma in javascript?

Question

how to print as follows in javascript ?

if my input is "smart" then my output could be "s,m,a,r,t"

I've tried by using this logic but i got the output as s,m,a,r,t,

let a = " ";
str = userInput[0];
console.log(str);
for (let i = 0; i < str.length; i++) {
  a = a + str[i] + ",";
}
console.log(a.trim());

You can use the split method in js

var str = "smart";
var res = str.split("").join();
console.log(res)
   //if you want it to remain an array don't do the join
