Scripts
JavaScript must be written inside the <script> tag in HTML. Scripts can be placed in either the <head>, <body> or both if need be. Scripts can also be placed in an external file and it’s more practical to use this method when many HTML documents make use of the same JavaScript.
JavaScript files have the extension .js
