Set the text content of the a tag to be the value stored in the variable inputValue

I'm really not sure why this is so difficult for me- am i not understanding the instructions correctly? Thanks!

app.js 
let inputValue = document.getElementById('linkName').value;
let a = document.getElementById('a');
a.textContent = inputValue;
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>

Hi Mike,

Your code shows 

let a = document.getElementById('a');

the 'a' is the tag name... what is the id name?

Let me know if you need more help.

Hi Elad, Thanks for the reply! That solves one of my problems but now I have this:

let inputValue = document.getElementById('linkName').value; let a = document.getElementsByTagName('a').textContent; a = inputValue;

and it still does not seem to be working..

Hi Mike,

Using 'getElementsByTagName' will give you an array, which means you'd have to use bracket notation -> []. Your code was actually really close the first time. My comment was to replace the 'a' with the id-name of the <a> tag, which is in the HTML. Your first attempt actually had the right code otherwise.

Elad.

document.querySelector('a').innerHTML = 'sdsdsds';
"sdsdsds"
document.querySelector('a').textContent = 'sdsdsdsndmf';
"sdsdsdsndmf"
document.getElementById('link').textContent = 'sdsdsds';
"sdsdsds"
document.getElementsByTagName('a')[0].textContent = 'dswwewewewe'
"dswwewewewe"
