Node.after()
Insert elements and strings after another element. Call the Node.after() method on the node you want to insert after, and pass in one or more new elements or strings as arguments.
<div id="app">Good morning</div>// Create a new element
let p = document.createElement('p');
p.textContent = 'Hello!';
// Get the target node
let app = document.querySelector('#app');
// Insert the new node after the target node
// <div id="app">Good morning</div><p>Hello!</p>
app.after(p);
// You can inject more than one item by passing in multiple arguments
// <div id="app">Good morning</div><p>Hello!</p>What's poppin'
app.after(p, `What's poppin?`);
