javascript native equivalent to .each & .attr

To fix this issue You're pretty close - forEach's first argument is the element you're iterating over, not the index. (In jQuery, the arguments are in reverse - the first argument is the index and the second argument is the item).
For the .attr('id') part, you can just access the plain .id property of the element:
document.addEventListener('scroll', function() {
  var anchor = document.querySelectorAll(".anchor");
  anchor.forEach(function(el) {
    if (isElementInViewport(el)) {
      if (window.history.pushState) {
        var urlHash = "#" + el.id;
        window.history.pushState(null, null, urlHash);
document.addEventListener('scroll', function() {
    function(el) {
      if (isElementInViewport(el) && window.history.pushState) {
        var urlHash = "#" + el.id;
        window.history.pushState(null, null, urlHash);

Equivalent of $(this) in native javascript

seems to work fine Within the event handler this will represent the element to which the event handler is bound. You will not have all of the utility functions provided by jQuery. So in your example you will not be able to retrieve the data attribute by using this.data("something")
To retrieve the value of the custom attribute the code must pass the event to the function. From the event or e in the example, the target property will contain the element that triggered the event, which may not always be the element to which the event handler was bound, due to the propagation of events. Use the getAttribute method to retrieve the value of custom attribute. Also refrain from making the custom attributes upper case as the html specifications do not allow for this and will create inaccessible attributes.
var menu = document.querySelector(".menu");
menu.addEventListener("click", function(e){

Javascript native equivalent to JQuery .each() & $(this)

it helps some times You're not going to find a native equivalent to $(this) because that is the jQuery function. There wouldn't be any reason to write the $ function if it already existed natively.
As for the .each part, you can work with any array like this:
var $comments = $('.comment');
comments.forEach(function(comment) { ... });
for (var i = 0, len = $comments.length; i < len; i++) {
    var comment = $comments[i];
var comments = document.getElementsByClassName('comment');
for (var i = 0, len = comments.length; i < len; i++) {
    var comment = comments[i];
    var content = comment.innerHTML;
    comment.innerHTML = html;
function boldComments() {
  const comments = document.querySelectorAll('.comment');
  comments.forEach(comment => {
    comment.innerHTML = '<b>' + comment.innerHTML + '</b>';

document.querySelector('button').addEventListener('click', boldComments);
  <li class="comment">Comment A</li>
  <li class="comment">Comment B</li>
  <li class="comment">Comment C</li>
  <li class="comment">Comment D</li>
<button>Bold comments</button>

Equivalent of .is() in jquery to native javascript

it fixes the issue Seems in this specific case you want to check if the element contains these two classes, if it is so then you can use document.querySelectorAll to get all the matched elements & check classList.contains to check if the element have that specific class
document.querySelectorAll('.product').forEach(function(item) {
  if (item.classList.contains('standalone') && item.classList.contains('expired')) {
.product {
  width: 100px;
  border: 1px solid red;

.colotText {
  color: green
<div class="product standalone expired">One</div>
<div class="product">Two</div>
<div class="product standalone expired">Three</div>
<div class="product">Four</div>
