Pagination in ejs

_paginate.ejs

<!-- provide these args: currentPage, totalPages, and queryParams -->
<!-- variables i and j control the number of pages to show on the left and right -->

<div class='pagination-container col-xs-12'>
    <ul class='pagination pagination-lg'>
        <% if (currentPage != 1) { %>
            <li><a class='ajax' href="/<%= paginateItem %>/?page=<%= currentPage - 1 %><%= queryParams%>">&laquo;</a></li>
        <% } else { %>
            <li class='disabled'><a class='ajax' href="javascript:void(0)">&laquo;</a></li>
        <% } %>

        <% var i = 5, j = 5; %>
        <% i += Math.max(0, currentPage + j - totalPages) %>
        <% j -= Math.max(0, currentPage + j - totalPages) %>
        <% for (var i; i > 0; i--) { %>
