Where to place Javascript

The script on the page will be executed immediately after the page is loaded into the browser. We don't always want this. Sometimes, we want to execute the script when the page is loaded, and in other cases, we want the script to be executed only when the user triggers the event.

Scripts in the head section:

When a script is called or an event is triggered, the script is executed. After you place the script in the head part, you can ensure that it has been loaded before you need to use the script.

Scripts in the body section:
The script is executed when the page is loaded. After you place the script in the body, it will generate the page content.
Scripts in the body and head sections:
You can place any number of scripts in the document, so you can place the script both to the body and to the head part.
