How to run JavaScript?

-2

In Chrome, I right clicked and select "inspect", and then I went "Console" tab. I wanted to practice JavaScript, so I typed

<script type="text/javascript">

and hit enter, but I got error message

Uncaught Syntax error: Unexpected Token<

Why?

That is a script tag, which is HTML. You can't run HTML in the console. That tag contains JavaScript, after the close of the tag in the question until the closing tag </script>.

The console defaults to run javascript so you need not specify

<script type="text/javascript">

this explicitly it understands so just try to run the javascript as it is and it should be working fine.

Thanks for your help. I'm learning Javascript. Here I skipped <script type="text/javascript"> and just typed "document.write("Hello World!");", but I got "Undefined" returned in the console. So do I need to define anything before using the function?

Coming to your question, you can practice JS in Console but you don't need to tell browser that you want to run javascript it know by default.

And <script> is a tag in HTML, read about it here https://www.w3schools.com/html/html_scripts.asp.
