Unless it is a Dynamic content which is placed by the server side scripts (very rarely used as there are many more better alternative methods) .. You can use JS in an external file ..
External js is re-usable .. I mean can be used by more than one HTML page .. So obviously it brings down the burden on browser ..
The site providing the live telecast or the NEWS/information (example:cricket scores etc) real-time examples for Dynamic content ..
