console.log in JavaScript

In this article, we will discuss console.log in JavaScript

Purpose

console.log is not a JavaScript’s standard feature. It is used to display data in web browser’s JavaScript console.

Example

Consider the following example

<!DOCTYPE html>
<html lang="en"
	xmlns="http://www.w3.org/1999/xhtml">
	<head>
		<meta charset="utf-8" />
		<title></title>
		<script>
        console.log("Test");
        document.write("test1");
    </script>
	</head>
	<body></body>
</html>

In the above example, I am using both console.log and document.write to display data in the web browser. Now run the above code and you will get following output.

As you can see in the above figure, the text written inside the console.log is not displayed in the browser. Because console.log is not meant for that purpose.
