What does '...' in React-Native mean?

A piece of react-native code:

enderScene(route, navigator) {   let Component = route.component;   return (<Component {...route.params} navigator={navigator}></Component>   );}

this code returns a Component Object ,

But I don't understand this code ---> {...route.params}

Question：

1. What is meant by '...' ?
2. Can you tell me what is meant by " {...route.params}" ?
