How to replace jQuery with Vanilla Javascript

1. Select something

Selecting element by class name. You can also use to select by tag or identifier:

  // jQuery
  $('.class-name');

  // ES6
  document.querySelector('.class-name'); // single

2. Select something within a parent

This example is similar to the one above: with an additional selection throught a parent element:

  // jQuery
  parent.find('.class-name');

  // ES6
  parent.querySelector('.class-name'); // single
  parent.querySelectorAll('.class-name'); // multiple

3. Add class

Adding a class into an element:

  // jQuery
  element.addClass('.class-name');

  // ES6
  element.classList.add('.class-name');

4. Remove class

Removing a class from an element:

  // jQuery
  element.removeClass('.class-name');

  // ES6
  element.classList.remove('.class-name');

5. Toggle class

  // jQuery
  element.toggleClass('.class-name');

  // ES6
  element.classList.toggle('.class-name');

6. Get attribute

  // jQuery
  element.attr('href');

  // ES6
  element.getAttribute('href');

7. Set attribute

  // ES6

  element.dataset.id = 1;

10. Get Text

  // ES6
  element.innerHTML;

12. Insert HTML string

  // ES6
  element.innerHTML = '<a href="https://www.gogle.com">Google</a>';

13. Insert text string

  });

    // ...
  });

  // jQuery
  object.each((key, value), function {
    // ...
  });

  // ES6
  for (const key in object) {

  }

  // or

    console.log(key, value);
  }

20. Add Event Listener

  // jQuery
  element.on( 'click', function(event) {
    // ...
  });

  // ES6
  element.addEventListener('click', (event) => {
    // ...
  });

21. Ajax request

  // jQuery
  $.ajax({
    url: 'https://example.com',
    method: 'post',
    dataType: 'json',
    contentType: 'application/json',
    data: JSON.stringify(data),
    success: function(response){
      // ...
    },
    error: function(error){
      // ...
    }
  });

  // ES6
  fetch( 'https://example.com', {
    method: 'post',
    headers: {
      'Accept': 'application/json',
