I have a javascript code like this
<script type="text/javascript">
window.onload=myFunction;
</script>
Is there any difference in using the above snippet in the <head></head> tag and just before
</body> tag, as I would like to call my function after the page loads.

basically there's no pratical difference, but I recommend
to place that code at the bottom, since you need to use a script (blocking-rendering tag) it's better put it at the end of the document.
to avoid a destructive assignments like that: writing window.onload=myFunction you destroy other previous assignments to window.onload event (if any) so it's better something like
(function() {
var previousOnLoadIfAny = window.onload;
window.onload = function() {
if (typeof previousOnLoadIfAny === 'function') {
previousOnLoadIfAny();
}
yourfunction();
}
}());
