How to rewrite in pure JavaScript code from JQuery code?

I have some trouble using JavaScript.

var $animation_left_right_elements = $('.bowl');

function check_if_facilites_in_view() {
    var window_height = $window.height();
    var window_top_position = $window.scrollTop();
    var window_bottom_position = (window_top_position + window_height);

    $.each($animation_left_right_elements, function() {
        var $element = $(this);
        var element_height = $element.outerHeight();
        var element_top_position = $element.offset().top;
        var element_bottom_position = (element_top_position + element_height);

        //check to see if this current container is within viewport
        if ((element_bottom_position >= window_top_position) &&
            (element_top_position <= window_bottom_position)) {
            $element.addClass('animationToRight');
        } else {
            $element.removeClass('animationToRight');
        }
    });
}

This is my JQuery code.

I checked this question convert jquery each function to pure javascript, but cannot solve my problem.
I want someone can help me. Thank you in advance.

Update

This is the code I tried.

var animation_left_right_elements = document.querySelectorAll('bowl');

function check_if_facilites_in_view() {
    var window_height = window.innerHeight;
    var window_top_position = $window.scrollY;
    var window_bottom_position = (window_top_position + window_height);

    animation_left_right_elements.forEach(function() {
        var element = this;
        var element_height = element.outerHeight();
        var element_top_position = element.offset().top;
        var element_bottom_position = (element_top_position + element_height);

        //check to see if this current container is within viewport
        if ((element_bottom_position >= window_top_position) &&
            (element_top_position <= window_bottom_position)) {
            element.addClass('animationToRight');
        } else {
            element.removeClass('animationToRight');
        }
    });
}

Answer

@GrafiCode said it’s good for me to answer my own question. This is my answer.

var animation_left_right_elements = document.querySelectorAll('.bowl');

function check_if_facilites_in_view() {
    var window_height = window.innerHeight;
    var window_top_position = window.scrollY;
    var window_bottom_position = (window_top_position + window_height);

    animation_left_right_elements.forEach(function(item) {
        var element = item;
        var element_height = element.scrollHeight;
        var element_top_position = element.offsetTop;
        var element_bottom_position = (element_top_position + element_height);
        var video = element.firstElementChild.firstElementChild;

        if ((element_bottom_position >= window_top_position) &&
            (element_top_position <= window_bottom_position)) {
            if (!element.classList.contains('animationToRight')) {
                element.classList.add('animationToRight');
            }
        }
    });
}
