document.getElementById().textContent not working with variable

Viewed 25503

When I use document.getElementById().textContent to set the "text content" to the value of a variable it doesn't work it doesn't to anything instead changing the text content to the value of the variable. It does work when I use

.textContent = "example";

but not

.textContent = example;

Here is my HTML

<head>
   <link rel="stylesheet" type="text/css" href="style.css">
   <script language="javascript" type="text/javascript" src="testScript.js"></script>
</head>

<body>
   <p class="heading">Heading</p>
   <p id="TextSpace"></p>


</body>

Here is my JS

//Get users name
var name = prompt("What is you name");
//put the name in the element "text space"
document.getElementById("TextSpace").textContent = name;

The prompt appears but after that nothing happens

Instead of putting the script tag at the bottom, you can just put defer and it will work perfectly fine

<head>
   <link rel="stylesheet" type="text/css" href="style.css">
   <script language="javascript" type="text/javascript" src="testScript.js" defer></script>
</head>

<body>
   <p class="heading">Heading</p>
   <p id="TextSpace"></p>


</body>
