Moving one element into another element in JavaScript

In this tutorial, we are going to learn about how to move one element inside another element in JavaScript.

Consider, we have two elements like this.

<div id="parent">
    <h1>I'm parent div</h1>
</div>

<div id="child">
    <h1>I'm child div</h1>
</div>

<button id="btn">Move element</button>

Now, we need to move the child into parent div like this.

<div id="parent">
    <h1>I'm parent div</h1>
    <div id="child">      <h1>I'm child div</h1>    </div></div>

<button id="btn">Move element</button>

Using the appendChild method

Inside the JavaScript first, we need to access the parent and child elements using document.getElementById() method then we need to use the appendChild() method to move child element into a parent.

The appendChild method inserts the specified element at the end of a parent node list.

const parent = document.getElementById('parent');
const child = document.getElementById('child');
const btn = document.getElementById('btn');

btn.addEventListener('click',()=>{
  parent.appendChild(child);})
