1. Create a JavaScript file

In VSCode, create a new file and set its extension to ".js". For example: "example.js".

2. Write JS code

Write your JavaScript code in the file. For example:

 <code class="js">console.log("Hello, world!");</code>

3. Install Node.js and npm

To run JS code, you need to install Node.js and npm on your system. These tools can be downloaded from the Node.js website.

4. Install Debugger for Chrome

In order to debug JS code in VSCode, you need to install the Debugger for Chrome extension.

5. Open the debug console

In VSCode, open the Debug console (or use the shortcut key Ctrl Shift D).

6. Select Chrome

In the Select Environment drop-down menu, select Chrome as your debugger.

7. Add a debug configuration

Click the "Add Configuration" button and select "JavaScript". Specify a name for the debug configuration, such as "Launch JavaScript".

8. Set up debug scripts

In the "Start Script" section, specify the path to the JS file to run. For example:

 <code class="json">{ "type": "node", "request": "launch", "name": "Launch JavaScript", "program": "${workspaceFolder}/example.js" }</code>

9. Run the code

Click the Run button or use the shortcut F5 to run your JS code.
