inputValue = document.querySelector('.info').textContent is wrong????

the second task made no sense, i wrote

inputValue = document.querySelector('.info').textContent; //this said i was wrong but these lessons never went over that it needs to read from left to write or right to left...i thought x=y and y=x was the same????

it only took the following code, why is that??

document.querySelector('.info').textContent = inputValue;

app.js
var inputValue = document.querySelector('input').value;
index.html
<!DOCTYPE html>
<html>
    <head>
      <title>DOM Manipulation</title>
    </head>
    <link rel="stylesheet" href="style.css" />
    <body>
      <div id="content">
        <label for="linkText">Link Text:</label>
        <input type="text" id="linkText" value="sample text">
        <p class="info"></p>
      </div>
    <script src="app.js"></script>
  </body>
</html>

The target of the assignment (the thing being changed) is always the term on the left of the = operator.

This wouldn't be covered in this specialty course, it would likely be in a preliminary course like JavaScript Basics.

oh wait, i think its because im CHANGING the .textContent to inputValue, not changing inputValue to the textContent since there is no text content to begin with correct???
