Do Java Script Prevent schema Markup from being displayed in Google search results

Here are 10 potential JavaScript issues that can prevent schema markup from being displayed in Google search results:

1. Incorrect implementation: If the JavaScript code is not properly implemented, or if it contains errors, it may prevent schema markup from being recognized by Google.

2. Conflicts with schema markup: If the JavaScript code conflicts with the schema markup, it may prevent the schema markup from being recognized by Google.

3. Dynamic content: If the JavaScript code is used to dynamically generate content, such as by pulling data from an API, it may prevent the schema markup from being recognized by Google.

4. Lazy loading: If the JavaScript code is used to lazy-load content, it may prevent the schema markup from being recognized by Google, as the schema markup may not be visible when the page is initially loaded.

5. Asynchronous loading: If the JavaScript code is loaded asynchronously, it may prevent the schema markup from being recognized by Google, as the schema markup may not be visible when the page is initially loaded.

6. Single-page applications: If the website is a single-page application, and the content is generated dynamically using JavaScript, it may prevent the schema markup from being recognized by Google.

7. Performance issues: If the JavaScript code is poorly optimized, or if it causes performance issues, such as slow loading times, it may prevent the schema markup from being recognized by Google.

8. Inadequate testing: If the JavaScript code is not properly tested, it may contain errors or conflicts that prevent the schema markup from being recognized by Google.

9. User-generated content: If the website allows users to generate content, such as through comments or reviews, the schema markup for this content may not be recognized by Google if it is generated using JavaScript.

10. Search engine limitations: Even if the JavaScript code is properly implemented and does not conflict with the schema markup, Google may not use the schema markup if it does not support the specific type of schema markup that is being used.
