        feature: [KeyframeableGeoJSONFeature](https://docs.maptiler.com/sdk-js/api-reference/types/KeyframeableGeoJSONFeature/),  
        options?: [ParseGeoJSONToKeyframesOptions](https://docs.maptiler.com/sdk-js/api-reference/interfaces/ParseGeoJSONToKeyframesOptions/),  
    ): [Keyframe](https://docs.maptiler.com/sdk-js/api-reference/types/Keyframe/)\[\][](#parsegeojsonfeaturetokeyframes)
    
    Converts a GeoJSON feature into an array of animation keyframes.
    
    Parses a GeoJSON feature with reserved properties to create animation keyframes. It extracts coordinates from the geometry and uses properties prefixed with '@' as animation control parameters (easing functions, delta values). Non-reserved properties are preserved and passed to the keyframe objects as props that will be interpolated
