What does the `t` filter do in this Liquid code? 🔤 ```liquid {{ 'products.product.add_to_cart' | t }} ```

### Explanation The `t` filter is used for internationalization in Shopify themes. It translates content based on the active language. Key points: - Purpose: - Retrieves translations from locale files - Enables multi-language support - Maintains consistent translations - Supports nested translation keys - Example usage: ```liquid {{ 'products.product.add_to_cart' | t }} ``` - How it works: 1. Takes a translation key (e.g., 'products.product.add_to_cart') 2. Checks the active language's locale file (e.g., fr.default.json) 3. Returns the corresponding translation 4. Falls back to default locale if translation missing - Best practices: - Use consistent key naming - Keep translations organized by feature - Always provide default translations - Use dot notation for nesting - Keep HTML in templates, not translations
