Q:

how to navigate back to splashscreen?

I have a test app that prints an array. what I need is, in the same place that is showing the printed array, a back button or make the available back button turn to the index.
Below is the code that prints the array when a button is pushed (second part of the code):  
function outputArray() {
for(var i=0;i<arr.length;i++){
document.write(arr[i]);
}

<button onclick="outputArray();">Print</button>

Can anyone help me.
Thanks,
Gilberto

A:

A splash screen is an image that appears while a game or program is
  loading. It may also be used to describe an introduction page on a
  website. Splash screens cover the entire screen or simply a rectangle
  near the center of the screen.

your question is nonsense ! splash screens are used to cover up loading times in smart phones.! 
if you want to go back use : 
history.back()
