insertAdjacentHTML is a DOM method you can call on any element to add new content to a page.

It is a nice and flexible way to insert new content.

The method is called on an element and accepts 2 parameters: the position, and a string containing HTML.

Here’s an example:

const item = `<div>
    test
  </div>
`

document.querySelector('#container').insertAdjacentHTML('afterend', item)

Notice the afterend string.

This is the position where the HTML is inserted relative to the container.

We have 4 possible positions:

• beforebegin before the element
• afterbegin before the first child of the element
• beforeend after the last child of the element
• afterend after the element

Here’s how we would add a new item to a list:

document.querySelector('ul').insertAdjacentHTML('beforeend', '<li>item</li>')
