You can use JS to display the output in different ways. Use window.alert() This function is used to display message alerts.
<!DOCTYPE html>
<html>
<body>
<h1>Code Projects</h1>
<p>Projects, Tutorials and More </p>
<script>
window.alert("ALERT");
</script>
</body>
</html>

The document.getElementById(id) method can be used in JS to access HTML elements. The Html element is defined by the id attribute, and the HTML content is defined by innerHTML.
<!DOCTYPE html>
<html>
<body>
<h1>Code Projects</h1>
<p>Projects, Tutorials and More </p>
<p id="ex"></p>
<script>
document.getElementById("ex").innerHTML = 50 + 50;
</script>
</body>
</html>
Output:
Use document.write( )
<!DOCTYPE html>
<html>
<body>
<h1>Code Projects</h1>
<p>Projects, Tutorials and More </p>
<script>
document.write(50 + 50);
</script>
</body>
</html>
document.write() after an HTML document will delete any existing HTML content:
<!DOCTYPE html>
<html>
<body>
<h1>Code Projects</h1>
<p>Projects, Tutorials and More </p>
<button type="button" onclick="document.write(50 + 50)">Click</button>
</body>
