      [null,null,["上次更新時間:2025-10-30 (世界標準時間)。"],[],["The core functionality involves extracting a specific property from a FeatureCollection using the `get(property)` method. This method requires the feature itself and the property name as input. The returned value is initially an `ee.ComputedObject`, which must be cast to the appropriate Earth Engine object type (e.g., `ee.String`) for further use. Examples demonstrate accessing property names via `propertyNames()` and extracting the 'provider' property from a power plant FeatureCollection in both JavaScript and Python.\n"]]
