    It seems to me that sometimes JavaScript can be placed anywhere in the HTML page, but sometimes it has to be in the <head> tag.

    Do anyone know the answer or any information on this?

    I think the only reasons for putting JS code in the head section are:

    1. It makes for more readable code.
    2. It prevents your JS functions being called before they're loaded.

    Scripts in the body section will be executed WHILE the page loads.

    Scripts in the head section will be executed when CALLED.

    While that is true, the opposite is also true.
