How to detect the browser language preference using JavaScript ?
Detecting the language preference of users can be very important for Websites or Web Apps for increasing user interaction. By using JavaScript, this task can be easily done by using:
Languages property is available for the navigator interface, which returns the most preferred / user preferred language set in the web browser. This property is read-only.
Syntax:
navigator.languages // Or navigator.language
Return Value:
- The navigator.languages property will return an array which stores the languages in an order in which language most preferred by the user will be the first element.
- The navigator.language property will return the first element of the array which is returned by the navigator.languages property i.e. the most preferred user language.
Note: Language property is a read-only property, thus it is only possible for us to get the value, we cannot make changes to the user preferred language.
Example 1: Getting the most preferred language.

<!DOCTYPE html><html> <body> <h1 align="left">GeekforGeeks</h1> <script> var usrlang = navigator.language || navigator.userLanguage; document.write( "User's preferred language is: " + usrlang); </script> </body> </html> |
