If I’m calling my JS scripts just before the closing body tag, is there a difference between using jQuery ready function like $(myfunc()); vs just using simply myfunc(); ?

    Only one difference would exist:

    When you use $(function(){...}) (short for$(document).ready(function(){...}), you’re automatically wrapping the code in an anonymous function, thus creating a private scope. Variables defined using var inside this scope aren’t leaked to the global scope.

    <script>
$(function(){ //<-- Anonymous function wrapper
   var test = 1; //"Private" variable
   alert(test); //Alert: 1
});
alert(window.test); //Nothing
</script>
<body>

    Versus

    <script>
var test = 1;
alert(test); //Alert: 1
alert(window.test); //Alert: 1
</script>
</body>

    When you don’t wrap the function call in a wrapper, both approaches have a similar result:

    <script>
$(myfunc);
</script></body>

</bodY><script>
myfunc();
</script>
