How to Run JavaScript in Chrome Browser?

To run JavaScript in the Chrome browser, you don’t need any special tools or software—Chrome has a built-in feature called the Developer Tools (DevTools) that lets you execute JavaScript directly. Here's how you can do it:

How to Run JavaScript in Chrome:

1. Open Chrome Developer Tools

• To get started, right-click on any part of a webpage and choose “Inspect” from the menu.
• Or use the shortcut Ctrl + Shift + I (on Windows/Linux) or Cmd + Option + I (on Mac).
• Then click on the Console tab at the top of the DevTools panel.

2. Use the Console

• The Console tab is an interactive environment where you can type and run JavaScript commands.
• Once you type a command, press Enter to execute it and see the result immediately.

Other Ways to Run JavaScript in Chrome:

3. Bookmarklets

• You can create a browser bookmark with JavaScript code in it. Clicking the bookmark will run the script on the current page.

4. Paste JavaScript into the Address Bar (with care)

• This method is limited due to modern browser security restrictions, but simple scripts can still be run using the javascript: prefix.

5. Create a Local HTML File

• Save your JavaScript in an HTML file and open it in Chrome. This is helpful for testing small projects.

Why Use DevTools Console?

• It’s the easiest and most flexible way to test JavaScript on any webpage.
• Great for debugging, learning, or experimenting with DOM manipulation.
