Bottom jQuery Insertion

I am noticing that jQuery can be inserted at the bottom of the page. Does this include all jQuery plugins too or will some need to be included at the top within the <head> tag?

And is it to do with an improvement in page load speed that jQuery is added last? I have always wondered, and I do use jQuery quite a bit, so I am finally getting around to asking. :slight_smile:

Thanks,

All JavaScript that is going to interact with the page should be attached at the bottom. Only JavaScript that is redirecting to another page without waiting for this one to load needs to go in the head. Since JQuery is written in JavaScript the bottom of the page is the correct place to attach it.
