title: React Native Function Call
body: <p>I am very new to react native and out of curiosity I want to know that whether we can call a function which is defined inside useEffect hook, outside of the hook? Like, everytime i refresh the page the function should be fired. I have thought of this approach, if any better solutions are available kindly guide. I am using a functional component. This is what i want to acheive:</p>
  <pre><code>RefreshControl component
   {somefunction()}
  
  useEffect(
  somefunction(){
  
  //function body
  }
      )
  </code></pre>
