Console.Log In Javascript

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

Purpose

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

Javascript Console

Now let us see, how we can use console.log in the JavaScript console. For doing that: -

Open the Chrome browser
Press F12
Go to the ‘console’ tab.
Enter console.log(‘test’)
Press the enter key
