Could you explain what means "return false" here? Why is it necessary? This is a jQuery code as you see. This code creates a click event for a button to get back to the top of the page.

<script>
$("bactToTop").click(function() {
    $("body").animate({scrollTop:0}, "slow");
    return false;
});
</script>

    @ScottMarcus, if it's a button, then it might prevent submitting a form, which might be desired. – rid May 27 '22 at 14:38

    @rid Using `event.preventDefault()` would be the best approach for those cases. – Scott Marcus May 27 '22 at 14:39

    @ScottMarcus - Or if you want to avoid having the click propagate to the ancestor elements. `return false` does both of those things, and is fully documented and clear to anyone used to working with jQuery. – T.J. Crowder May 27 '22 at 14:39
