To use JavaScript in Google Analytics, you need to implement the Google Analytics tracking code on your website or mobile app. Here is a step-by-step guide on how to do it:

1. Sign in to your Google Analytics account.
2. Create a new property or select an existing one.
3. In the Admin section, under the Property column, click on "Tracking Info" and then "Tracking Code".
4. Copy the provided tracking code, which begins with "", where GA_TRACKING_ID is your unique tracking ID.
5. Paste this tracking code within the section of your website's HTML code or directly before the closing tag.
6. Save and publish your changes to your website.
7. Open any page of your website in a web browser and go to the Google Analytics Realtime Reports section. If your tracking code was implemented correctly, you should see data being tracked in real-time.

Once the tracking code is implemented, Google Analytics will start collecting data about your website or app usage, such as page views, events, and conversions. You can then use JavaScript methods and functions provided by Google Analytics to customize your tracking and send additional data, like custom dimensions, events, or eCommerce transactions.

Additionally, you might need to configure specific features, such as Enhanced Ecommerce or cross-domain tracking, by following the documentation provided by Google Analytics.
