why doesnt the persian word add behind a number?

Question

i have a really strange problem in java script. look at these codes and run the app:

const number = 200000;
const persianMoney = "تومان";

//pay attention to these lines:
console.log("way 1:");
console.log(number + persianMoney);
console.log(persianMoney + number);

console.log("way 2:");
console.log(`${number}${persianMoney}`);
console.log(`${persianMoney}${number}`);

console.log("way 3:");
console.log(String(number) + persianMoney);
console.log(persianMoney + String(number));

console.log("way 4:");
console.log(`${String(number)}${persianMoney}`);
console.log(`${persianMoney}${String(number)}`);

console.log("way 5:");
console.log(String(number + persianMoney));
console.log(String(persianMoney + number));

all of the outputs are the same!! all of the outputs are 200000تومان! but why word تومان is not behind 200000 in some outputs? even here, i cant put تومان behind 200000! but why it is like that? i cant understand it. i tested concatenation in 5 ways but none of them were correct! how can i solve this problem? thanks for helping.

Answer 1

As stated by Raymand Chen. My understanding is that you want to have the currency name تومان after the number 200000. To keep the Arabic/Persian word in the same direction as the Latin word i.e. in a Left-To-Right LTR direction.

One possible way to do that is to add the LTR code \u200E

const number = 200000;
const persianMoney = "تومان";
const ltr = "\u200E";
console.log(persianMoney + ltr + " " + number);
