- Create a html file, say
index.html- Create a js file beside it, say
script.js- Connect the js file to the html file via script tag
<script src="script.js"></script>
With the files set up, open the HTML file in your browser and move on to editing the JS file.
- Install VS code text editor on your system.
- Install the extension called Live server in VS code.
- Right click on
index.html- Select Open with live server
- Right click on the webpage in your browser
- Select Inspect
- Developer tools is opened
- Go to Console to find the output of your javascript commands
- Whenever you edit the js file and save it, immediately output is shown in the console
Note
You can also execute js commands directly in console of any webpage
