Responsive Navigation Cache Component

Question

I am new to ReactNative and a bit confused about the following. I installed StackNavigator as shown

const MyProjectNavigator = StackNavigator({
  home: {screen: Other},
  latest_news: {screen: LatestNews}
}

When I want to switch to another screen, navigation, I do the following:

navigate(
      latest_news, {
        otherParams : param1
      }
    ); 

It works well so far.

Now suppose that the last_news component requests a large amount of data from the server when it is installed, then it performs many operations on this data, sorting by date, author, yadda yadda. It will take some time.
