My question is simple, but I have not found any answer for this.
1. Where should I place the jquery library? in the body or head? I'm asking about the jquery library, not about my jquery's.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
2. Is there any problem if I put MY jquery's in the end of body with:
$( document ).ready(function() {
? I know I need this in the head, not in the body, what I want to know is if it can slow my page or something like this, because I want to leave this tag if in the future I decided to place it in head again.
