please help me

The question is : Inside the click handler in app.js:

  • Select the heading text with the class of .profile-name
  • Use jQuery’s text() method to set the contents of .profile-name to the value of the input field

The error is: SyntaxError: app.js: Assigning to rvalue '$' (4:2)

I have no idea why this error occurs. please help me!

index.html 
<!DOCTYPE html>
<html lang="en">
<head>
    <title>Document</title>
</head>
<body>
    <h2 class="profile-name">Treasure Porth</h2>
    <p class="profile-text">I am a web developer!</p>

    <label>Change name:<input id="name-input" type="text"></label>
    <button>Change</button>

    <script
    src="jquery-3.2.1.min.js"></script>
    <script src="app.js"></script>
</body>
</html>
app.js 
$('button').click(function() {

  var newName=$('#name-input').val();
  $('#profile-name').text() =newName.val();


});

Hey, there are two mistakes in your code.

  1. profile-name is a class not an id
  2. to change the text content of a selector, you have to pass the new value as an argument to the text() function

this should work:

$('button').click(function() {
    var newName=$('#name-input').val();
    $('.profile-name').text(newName);
  });
