how do I use javascript to extract some data into a variable?

Question

I need to extract some data

<span class="btn btn-orange" 
      style="visibility: visible; cursor: pointer;" 
      onclick="javascript:showPixelId(250);" 
      data-mpn-code="7290108862140" 
      data-color="#2695d8" 
      data-initialized="true">Acquista Online</span>

I have this code and I want the 7290108862140 to be returned into a javascript variable

There is no specific event. The information is on a product page and I want to extract this numer into a variable so I can use it. — RBongie, Jul 24 '19 at 09:26

If you want to get the data to handle:

let span = document.getElementBy('btn-orange');
let mpnCode = div1.getAttribute('data-mpn-code');
let color = div1.getAttribute('data-color');
let initialized = div1.getAttribute('data-initialized');

or just use it directly. For example:

let span = document.getElementBy('btn-orange');
console.log(div1.getAttribute('data-mpn-code'));
console.log(div1.getAttribute('data-color'));
console.log(div1.getAttribute('data-initialized'));

//output:

7290108862140

#2695d8
