The $product object in WooCommerce provides developers access to all relevant product data. If you're customizing WooCommerce templates or building advanced features, here's a reference of what you can retrieve:

1. ID: $product->get_id() – Get the product ID.
2. Name: $product->get_name() – Title of the product.
3. Type: $product->get_type() – Type (simple, variable, etc.).
4. SKU: $product->get_sku()
5. Description: $product->get_description()
6. Short Desc: $product->get_short_description()
7. Regular Price: $product->get_regular_price()
8. Sale Price: $product->get_sale_price()
9. Stock Qty: $product->get_stock_quantity()
10. Weight: $product->get_weight()
11. Dimensions: $product->get_dimensions()
12. Categories: $product->get_category_ids()
13. Tags: $product->get_tag_ids()
14. Gallery: $product->get_gallery_image_ids()
15. Featured Image: $product->get_image_id()
16. Attributes: $product->get_attributes()
17. Variations: $product->get_available_variations()
18. Rating: $product->get_average_rating()
19. Reviews: $product->get_review_count()
20. Permalink: $product->get_permalink()
21. Add to Cart URL: $product->add_to_cart_url()
22. Cart Button Text: $product->add_to_cart_text()

These methods provide everything from basic details to advanced product metadata. If needed, inspect the full $product object using print_r() or var_dump(). This makes custom WooCommerce development more efficient and powerful.
