jquery - When do you choose to load your javascript at the bottom of the page instead of the top?

Question

I have seen JavaScript libraries being loaded at the top and bottom of the page.

I would love to know when to make these choices. All the JavaScript code I've written all work at the top of the page, which includes jquery plugins.

When do i load my script at any of these positions?

Answer 1

Top: When having JavaScript events function on elements immediately is more important (so if you use a DOM Ready event to load everything, this is the wrong place)

Bottom: When loading the content is more important
