I am attempting to utilize Angular JS version 1.2.1, but encountering issues when trying to implement it outside of JSfiddle.

There could be several reasons why you are encountering issues when trying to implement AngularJS outside of JSfiddle. Some possible solutions are:

1. Make sure you have included the correct script files: AngularJS consists of several script files, including the main angular.js file and various modules. Make sure you have included all the required script files in your HTML file.

2. Check for conflicts with other libraries: AngularJS can sometimes conflict with other JavaScript libraries like jQuery. Make sure you have included the libraries in the correct order and have resolved any conflicts.

3. Check for typos in your code: AngularJS directives, expressions, and controllers have a specific syntax. Make sure you have followed the correct syntax and have not made any typos in your code.

4. Verify that your module is properly defined: AngularJS applications are built using modules, which define the application components. Make sure you have properly defined your module and included it in your HTML file.

5. Check for console errors: Use the browser console to check for any errors or warnings that may be preventing AngularJS from working properly. Fix any errors that you find.

6. Make sure you have included ng-app: The ng-app directive tells AngularJS which part of your HTML code represents the AngularJS application. Make sure you have included this directive in your HTML code.

By following these steps, you should be able to successfully implement AngularJS in your project.
