Why doesn't this work in JS ? I need to keep on adding a value to empty in for loop

let lang = "";
lang[0] = "J";
lang[1] = "S";
console.log(lang);//''

Why it sets to empty string ?

I was expecting 
let lang = "";
lang[0] = "J";
lang[1] = "S";
console.log(lang);//JS

JavaScript strings are immutable. – Robby Cornelissen May 29 '23 at 06:13

You cannot write to strings. They are read-only. You can however assign a new string to your variable: `lang = lang + "J"` – slebetman May 29 '23 at 06:28
