🧭 Navigator Object

Last Updated: 26th October 2025

The Navigator Object provides information about the browser and operating system in which JavaScript is running.
It is a property of the window object, so you can access it as window.navigator or simply navigator.

Hinglish Tip 🗣: navigator browser ka “ID card” hai — ye batata hai ki kaunsa browser, platform, language, aur network use ho raha hai.

Example

console.log("Browser Name: ", navigator.appName);
console.log("Browser Version: ", navigator.appVersion);
console.log("User Agent: ", navigator.userAgent);
console.log("Platform: ", navigator.platform);
console.log("Language: ", navigator.language);
console.log("Online Status: ", navigator.onLine);

User Current Location

navigator.geolocation.getCurrentPosition(
  (position) => {
    console.log("Latitude: " + position.coords.latitude);
    console.log("Longitude: " + position.coords.longitude);
  },
  (error) => {
    console.error("Error: " + error.message);
  }
);

Hinglish Tip 🗣: Geolocation tabhi kaam karega jab user permission de. Browser popup me “Allow Location Access” dena padta hai.
