1. **What is the purpose of the `settings_schema.json` file in a Shopify theme?**
   - *Answer*: The `settings_schema.json` file is used to define the customizable options available in the theme editor. It specifies the types of settings (e.g., text, color, image) that users can modify without directly editing the code.

2. **Explain the role of the `settings_data.json` file in a Shopify theme.**
   - *Answer*: The `settings_data.json` file contains the actual values chosen by the user in the theme editor for the customizable options defined in the `settings_schema.json`. It stores the configuration data that determines how the theme will appear and behave.

3. **What is the purpose of the `sections` folder in a Shopify theme?**
   - *Answer*: The `sections` folder contains Liquid files that define customizable components of a page, such as headers, footers, product grids, and more. Sections allow for a modular approach to building Shopify themes, making it easier for users to customize their store's layout.

4. **Explain the difference between a `section` and a `block` in a Shopify theme.**
   - *Answer*: A `section` is a larger, customizable component of a page (e.g., a product grid), while a `block` is a smaller unit of content within a section (e.g., an individual product card). Blocks are the building blocks that make up a section.

5. **How many block types are there in Shopify Liquid for creating blocks?**
   - *Answer*: Shopify Liquid provides three types of blocks for creating content within a theme: `{% schema %}`, `{% stylesheet %}`, and `{% javascript %}`.

6. **What is the purpose of the `templates` folder in a Shopify theme?**
   - *Answer*: The `templates` folder contains Liquid files that define the structure and layout of specific pages, such as product pages, collection pages, and the cart page. These templates control how content is displayed on different types of pages.

7. **Explain the difference between a Shopify theme and a Shopify app.**
   - *Answer*: A Shopify theme is responsible for the appearance and layout of an online store, controlling the front-end presentation. A Shopify app, on the other hand, adds functionality or features to the store, often modifying back-end behavior or providing additional tools.

8. **How can you add custom JavaScript or CSS files to a Shopify theme?**
   - *Answer*: Custom JavaScript or CSS files can be added to a Shopify theme by uploading them to the `assets` directory within the theme. Once uploaded, they can be referenced in the theme's Liquid or HTML files using appropriate script or link tags.

9. **Explain the purpose of the `locales` folder in a Shopify theme.**
   - *Answer*: The `locales` folder contains translation files that allow a theme to be multilingual. It provides the ability to display content in different languages to cater to a global audience.

10. **What is the role of the `config` folder in a Shopify theme?**
    - *Answer*: The `config` folder may contain various configuration files specific to the theme, which can include files for metafields, theme settings, and other custom configurations.
