I am learning to inject JS script into an HTML. But I don't understand why this code does not work - does not show the alert when loading the window but the script tag is shown properly when inspecting the page
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<div></div>
<script>
const container = document.querySelector("div");
container.innerHTML = "<script>alert(123)<\/script>";
</script>
</body>
</html>
