Is java script always inside the html file, or is it its own file like css

Answer 1

they used to put the long or general javascript codes in their own file, so they can reuse them in different pages and also it's easier to read.

Answer 2

All developers put it in extra file like CSS.....now you will ask some pages have script in it isn't it ...they are created by Dreamwave or bluegriffin or others 😉
