How to select "info" class within "p" element and set it's textContent?

Created a variable called inputValue, now I'm trying to set the textContent of the "info" class in the "p" element to that value.

Here's the code I thought should work:

const inputValue = document.querySelector("input").value; // this is showing as correct

// then I'm trying to use the below function to set the textContent
() => {
document.querySelector("p .info").textContent = inputValue
const inputValue = document.querySelector("input").value;
() => {
  document.querySelector("p .info").textContent = inputValue;
<!DOCTYPE html>
      <title>DOM Manipulation</title>
    <link rel="stylesheet" href="style.css" />
      <div id="content">
        <label for="linkText">Link Text:</label>
        <input type="text" id="linkText" value="sample text">
        <p class="info"></p>
    <script src="app.js"></script>

document.querySelector("p .info") selects an element with the class info that is contained in a p element. The challenge is expecting an element that both is a p element and has the class info, which would be document.querySelector("p.info")

() => {
document.querySelector("p .info").textContent = inputValue

creates an anonymous function, but never calls it. To call the function, you could change it to

(() => {
document.querySelector("p .info").textContent = inputValue
}) ()

with parentheses around the function, and () at the end to call it.

The challenge does not require you to use a function. You could simplify your code to document.querySelector("p .info").textContent = inputValue
