Cant's solve the task

Can't solve the task. Can someone help me to figure out what to do?

app.js 
let aTag = document.querySelector('a');
let inputValue = aTag.textContent;
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>

You need to select the input(#linkName) for the value and select the a(#link) element to store the value of the input to its textContent property.

let inputValue = document.querySelector("#linkName").value;
let a = document.querySelector("#link");

a.textContent = inputValue

Set the text content of the a tag to be the value stored in the variable inputValue aTag.textContent = inputValue;

Why don't we need to invert them? Task says that we need to store text content of a tag in the inputValue

They ask for the content of the a element to be filled with the value of the input. So what they want to achieve is that if you tip something in the input bar it comes into the a element. so no not invert them. And glad that I could help. :)
