God DOM is hard... help(!)

Again, tried every possible outcome i can think of, both with the var += and the var = combinations... totally lost atm😤

app.js 
var inputValue=document.querySelector("input, #linkName").value;
inputValue += document.querySelector("input a, #link");
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>

Perhaps all you need is a few hints:

  • ID's are unique, so when selecting something with an ID you need only the ID
  • in task 2, you need to access the textContent of the element
  • since task 2 is updating the document, the selector and property will be left of the assignment operator
  • the value you retrieved in task 1 will be on the right of the assignment in task 2

Really close now! Since "textContent" is a property and not a method, you won't need parentheses after the name. And the instructions call for a simple assignment ("=") instead of an addition assignment ("+=").

And just to be sure, you'll need to leave your task 1 code line as-is and add the new one after it.
