I don't know how to solve task 2 of this exercise to add the text content of the Anchor tag to the input value

I don't know how to solve task 2 of this exercise, to Set the text content of the a tag to be the value stored in the variable inputValue.

app.js 
const input = document.querySelector('input');
let inputValue = input.value;
index.html 
<!DOCTYPE html>
<html>
    <head>
        <title>DOM Manipulation</title>
    </head>
    <link rel="stylesheet" href="style.css" />
    <body>
        <div id="content">
            <label>Link Name:</label>
            <input type="text" id="linkName">
            <a id="link" href="https://teamtreehouse.com"></a>
        </div>
        <script src="app.js"></script>
    </body>
</html>

So the aim is to set the value of the input element to the variable inputValue

First we need to locate the HTML input element using javascript.

document.getElementById('linkName')

Then we need to access the value data for the input element.

document.getElementById('linkName').value

We can do this by adding the .value to the end of the element locator.

Finally save this to the variable:

inputValue = document.getElementById('linkName').value

Jamie, that's another way to solve task 1 but the question is about task 2.

Task 2 is almost the opposite of task 1. Instead of putting a value from a form element into a variable, in task 2 you will put the value from that same variable into another element.

So the terms will be on opposite sides of the assignment, and you'll use a different selector and access a different property.

I'll bet you can get it now without an explicit spoiler.

you need to use similar methods. The key thing here is that you need to target the link.

document.getElementById('link').innerHTML = inputValue
