Console.Log In Javascript

This article describes console.log in JavaScript.

Purpose

Console.log is not a core feature of the JavaScript language itself; rather, it is a function provided by web browsers to output messages to the JavaScript console, typically used for debugging purposes.

Example

Consider the following example: -

<script>
 console.log("Test");
 document.write("test1");
</script>

Try It

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

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

Javascript Console

Let us see how we can use console.log in the JavaScript console. To do this:

Open the Chrome browser.
Press the F12 key on the keyboard.
Go to the Console tab.
Write the code console.log(‘test’).
Press the Enter key.
