The Number toLocaleString() method
Find out all about the JavaScript toLocaleString() method of a number
Formats a number according to a locale.
By default the locale is US english:
new Number(21.2).toLocaleString() //21.2
We can pass the locale as the first parameter:
new Number(21.2).toLocaleString('it') //21,2
This is eastern arabic
new Number(21.2).toLocaleString('ar-EG') //٢١٫٢
There are a number of options you can add, and I suggest to look at the MDN page to know more.
