Error: The function m.easing[this.easing] is not defined

I have been working on creating anchor link scrolling and tooltip display using bootstrap, but I am encountering an issue.

$(window).scroll(function(){
    if ($(window).scrollTop() >= 100) {
       $('#header').addClass('fixed');
    }
    else {
       $('#header').removeClass('fixed').fadeOut("slow", 100);
     }
            $('[data-toggle="tooltip"]').tooltip();  
});


$(function() {
    $('a.page-scroll').bind('click', function(event) {
        var $anchor = $(this);
        $('html, body').stop().animate({
            scrollTop: $($anchor.attr('href')).offset().top
        }, 1500, 'easeInOutExpo');
        event.preventDefault();
    });
});

$(function() {
    $('a.scroll').bind('click', function(event) {
        var $anchor = $(this);
        $('html, body').stop().animate({
            scrollTop: $($anchor.attr('href')).offset().top
        }, 1500, 'easeInOutExpo');
        event.preventDefault();
    });
});

Upon checking the console, I found an error message stating "TypeError: m.easing[this.easing] is not a function". This seems to be causing some trouble with the functionality.

As per the documentation on fadeOut, the duration of the animation should be the first argument and the callback should be the second argument. The duration can either be specified in milliseconds (as seen in your code) or as a string representing timeframes.

To fix this issue, you need to adjust your fadeOut code in one of the following ways:

$('#header').removeClass('fixed').fadeOut("slow");

// OR

$('#header').removeClass('fixed').fadeOut(100);

It seems that you are using the easing function easeInOutExpo, which is not a part of the default jQuery library. You can refer to this page for information on available easing functions:

jQuery only includes two easing functions by default - 'swing' and 'linear'. For more easing options, you may need to use plugins, such as those provided in the jQuery UI suite.

In order to utilize the easeInOutExpo easing, make sure to include jQuery UI as an external library on your webpage.

Moreover, jQuery UI is also required for the tooltip method to work correctly.
