Navigator in JavaScript

The window.navigator object contains information about the visitor’s browser.

Window Navigator

The window.navigator object can be written without the window prefix.

//Example

navigator.appName
navigator. appCodeName
navigator.platfornm

---

Browser Platform

const platform = navigator.platform
console.log(platform) //MacIntel

---

Browser Language

const language navigator.language 
console.log(language) // ["en-GB", "en-US", "en"]

---

Is The Browser Online?

const onLine navigator.onLine
console.log(onLine) // true

Warning !!!

The information from the navigator object can often be misleading, and should not be used to detect browser versions because:

Different browsers can use the same name The navigator data can be changed by the browser owner Some browsers misidentify themselves to bypass site tests Browsers cannot report new operating systems, released later than the browser.

---

Browser Cookies

const isCookieEnabled = navigator.cookieEnabled
console.log(isCookie Enabled) //true

---

Browser Application Name

const appName = navigator.appNane 
console. log(appNane) //Netscape

//Strange enough, "Netscape" is the application name for both IE11, Chrome, Firefox, and Safari.

Browser Application Code Name

const appCodeName = navigator.appCodeName
console. log(appCodeName) //Mozilla

//Mozilla is the application code name for both Chrome, Firefox, IE, Safari, and Opera

Browser Engine

const product navigator.product 
console.log(product) //Gecko 

//Do not rely on this. Most browsers returns "Gecko" as product name
