The toLocaleString() method converts a number into a string, using a local language format. The language depends on the locale setup on your computer.
Syntax:
number.toLocaleString(locales, options)
Parameters: This method accepts two parameters locales and options.
- locales: This is an optional parameter. It specifies the language format to be used.
- options: This parameter is also an optional one.
- It includes maximumFractionDigits that represent a number from 0 to 20 (default is 3)
- It includes maximumSignificantDigits that represent a number from 1 to 21 (default is 21).
Note: There are other options as parameters such as minimumFractionDigits, minimumSignificantDigits, currency, and many more. The developer can use them as per the requirement of the application.
Return value: The return value can be a string that represents a number.
